Jokes aside, I have been blocked many times by overzealous email validation. Yes, my email has a plus sign in it. This is allowed under RFC5322, so deal with it. It is better to have no validation at all than incorrect validation.

A plus sign? That's nothing, LOL

I like this issue in the form of a quiz

TIL:
🫱@🫲
is a valid e-mail address.

[-] smiletolerantly@awful.systems 4 points 1 week ago

Nice, I was able to send an email to that.

[-] erer@lemmy.zip 4 points 1 week ago

I dont know if it's just me, but this comment is breaking the rendering of Voyager

[-] elvith@feddit.org 3 points 1 week ago

I needed to use a code block for that address as several apps had a problem when I tested escaping the back ticks in the address for the inline code. Not sure if you mean that as it renders in it's own line or if anything else is broken

[-] mormegil@programming.dev 4 points 1 week ago

Because of one smartass customer who insisted on doing exact RFC 822 validation, I implemented exactly that. And yes,

zKcknV|NGv.lI66vR#@X`QcRK4K.R`?NpA.Gc2Kqzue9.%&nb1kGWp/./#Och$RQv

is one of the test cases for a valid addr-spec. See (or generate) some others at https://github.com/mormegil-cz/rfcemailvalidator

[-] gegil@sopuli.xyz 87 points 2 weeks ago

The best email validation is just sending an email to whatever provided by the user. If user receives an email and validates it, than its validated.

[-] kunaltyagi@programming.dev 14 points 1 week ago

Email address spec is convoluted and this is indeed the best way. Noobs and ninja do it this way, normies try to validate before sending email

The worst sites are the ones that let you sign up with an unusual address but not log in. The worst I‘ve seen was some ticket system that rejected dfyx+theirdomain@mydomain after I clicked the link in their confirmation email.

[-] FishFace@piefed.social 20 points 2 weeks ago

There's an aspect of my surname which is somewhat unusual (at least in my country). As a result I occasionally get form validation errors when entering it. Sometimes those errors are extremely inscrutable. Sometimes a form validates but something elsewhere makes unvalidated assumptions about names which then breaks in completely unpredictable names...

[-] TurtleTourParty@midwest.social 18 points 2 weeks ago
[-] FishFace@piefed.social 6 points 1 week ago

Actually no. In fact, I think most people who thought for a minute would realise names like mine exist, it's just that sometimes people working systems don't think for a minute ;)

[-] purplemonkeymad@programming.dev 8 points 1 week ago

The number of scripts I've seen that would break with an O'Neill or O'Brien is too high. Worse is some people don't get it when pointed out.

[-] douglasg14b@lemmy.world 34 points 2 weeks ago

Even worse is when they strip the plus sign out after the fact and then you can't log in anymore because you didn't realize that's what has happened.

[-] filcuk@lemmy.zip 15 points 2 weeks ago

This is criminal. You already send me a validation email, just check for an @ and leave me be

[-] dogs0n@sh.itjust.works 11 points 1 week ago

Yees this has happened to me before but with passwords. They have some length limit that they clamp to so you can't login after registering and I have to do a password reset right after signing up. Happened multiple times to me.

[-] SmoothLiquidation@lemmy.world 31 points 2 weeks ago

I had a website not let me enter a proton.me email address, when I changed it to my custom.fyi address, it worked fine. They wanted a three letter TLD.

[-] Scrollone@feddit.it 14 points 2 weeks ago

No, I think they just blocked Proton email addresses. I've seen multiple services doing that.

[-] kossa@feddit.org 15 points 1 week ago

That was my best customer support interaction ever. Company did not let me register with a "new" TLD email address, as "this is not a valid email address". I wrote them from that email address. They respondend to that email address with "this is not a valid address". I wrote back "how are we writing, then?" and never heard back 😂

[-] traxex@lemmy.dbzer0.com 14 points 2 weeks ago

Not sure if you also do aliases as well but I’ve seen an increase in websites flagging providers like addy.io as well. Extremely annoying that so many websites think they are so important that they refuse an alias.

[-] borari@lemmy.dbzer0.com 11 points 2 weeks ago

I had a site refuse my email address for my .net domain. Like wtf, if it’s not .com it’s not a real email address? Idk what that was about.

[-] grendel84@tiny.tilde.website 7 points 2 weeks ago

@traxex
@ooterness

migadu has a cool workaround.

instead of:
alias+user@domain.tld

you give:
alias@user.domain.tld

then internally it transforms it to an alias when it comes in.

[-] Scoopta@programming.dev 10 points 2 weeks ago

Same although for a totally different reason. There are some services that really don't like gtlds and they will say your address is invalid if it doesn't end in .com, .net, or .org...all my serious domains are gtld...so some services have emails on meme domains because the only domains I have with traditional tlds are memes

[-] dohpaz42@lemmy.world 65 points 2 weeks ago* (last edited 2 weeks ago)

The issue this is referring to is because the user cannot paste into a text field. And the user was not rude about it either.

So instead of fixing the actual problem, the developer went nuclear and removed the validation. A dick move in my opinion given the developer’s attitude.

~It’s more sad than funny. 🤷‍♂️~

[-] theit8514@lemmy.world 25 points 2 weeks ago

IMO as a developer this is a sane change. There's no telling when the format of the first-party api key will change. They may switch from reference tokens to JWT tokens tomorrow. The validation should be using the token and seeing if it works.

[-] Dupelet@piefed.social 6 points 2 weeks ago

If they had made the change for that reason, sure. But the actual stated cause was some pretty thing.

[-] wheezy@lemmy.ml 10 points 2 weeks ago

I don't know what that repo does. But, chances are the dude was just fucking tired of dealing with curseforge. Total garbage scum software.

[-] douglasg14b@lemmy.world 5 points 2 weeks ago

It's prism. A multi-launcher for Minecraft Java edition.

[-] dogs0n@sh.itjust.works 3 points 1 week ago

I'm guessing removing the validation fixed the pasting, which means it did fix the actual problem?

[-] mogranja@lemmy.eco.br 42 points 1 week ago

I hate when websites have some weird rules for passwords, and show the rule when you are creating the password, but not when entering it. How am I supposed to remember the password must begin and end with a special character?

[-] FooBarrington@lemmy.world 35 points 1 week ago

I can't recommend password managers enough, because you will never have this issue again.

[-] wasabi@feddit.org 8 points 1 week ago

Password creation will still be annoying for sites with special rules. You just don't have to remember them once you generated them.

[-] FooBarrington@lemmy.world 4 points 1 week ago

I've literally never had an issue with password generation. Usually I generate 32 character passwords with all types of characters passwords on average expect. If a page has different rules, I just check the corresponding boxes in my password manager, and I get one that works for that site.

[-] protogen420@lemmy.blahaj.zone 18 points 1 week ago* (last edited 1 week ago)

and when the rule is also wrong example: password must contain special charcters

the password in question contained : and ^

if those aren't special characters idk what is

[-] sus@programming.dev 13 points 1 week ago* (last edited 1 week ago)

maybe they were looking for extra special characters like 🁄 or ⶸ. Who am I kidding, RFC 1738 tells us that literally everything is unsafe and you know, we need to prepare for the inevitable occasion when the password somehow ends up inside an URL.

The characters "<" and ">" are unsafe because they are used as the delimiters around URLs in free text;
the quote mark (""") is used to delimit URLs in some systems.
The character "#" is unsafe
The character "%" is unsafe

It ends up with

Thus, only alphanumerics, the special characters
$ - _ . + ! * ' ( ) ,
are safe

[-] planish@sh.itjust.works 5 points 1 week ago

If the password is going in URLs you already have a problem.

Having to alter my one generic password I use for random ass website because there's a stupid extra rule is usually annoying me enough that I don't register lmao.

[-] Phoenix3875@lemmy.world 12 points 2 weeks ago

So the users realized their mistakes and stopped complaining……and other jokes public project maintainers tell themselves while laughing in tears

Prismlauncher! I remember browsing through the changelog and spotting this, made me chuckle internally.

[-] lukalix98@programming.dev 5 points 2 weeks ago

If only I had a penny each time a user told something doesn't work when it shouldnt've.
