I don't understand the thought process here. Like many, I don't browse Communities individually, I browse /All and sort by New.
So I am required to see something I like and upvote or else I am not allowed to an express an opinion in the community (or any tangentially linked community)?
If I see something I don't like (which is what the voting system is for), I should go to the Community it's posted in and make sure to upvote things before I downvote? That's the expected order of operations?
If not... what if, while browsing /All /New nothing randomly appears that the viewer likes enough to upvote? Is that then somehow the fault of the viewer and they should then be banned?
Am I interpreting your rulings correctly? 4 downvotes in the span of 10 months (judging by the times on those posts you listed) is a bannable offence? Seems rather heavy-handed to me.
It's perfectly distinguishable unless you're trying real hard to misinterpret what I said. As a Mod of a small Community myself, here's the difference in downvotes:
Bad Faith Actor: Sees a post or a whole Community they don't like. Goes in and systematically downvotes a bunch of stuff on purpose. Topics, responses... everything. Downvotes because they hate the community and everything it stands for. See 50 downvotes in your Community in one day? That's these fuckers. Ban them. They are assholes and are vote manipulating. Probably ban them from related Communities for vote manipulation.
Normal User: (--> We are here) May or may not comment in YOUR Community, especially if it's image-based. Sees a single post that they don't like out of thousands they see daily and downvotes it. Several months later, it may happen again. This is expected behaviour and is how an upvote / downvote system functions. Don't ban these or you're the asshole.
Brigade Users: A coordinated attack to downvote or spam a Community stemming from some other place. They downvote everything and often post garbage. Ban these people. They are assholes and are vote manipulating. Probably ban them from related Communities for vote manipulation if not trying to seek an instance ban.
Lurker: (The overwhelming majority of users are this) Indistinguishable from a Normal user in votes, but may not comment. May be an alt or bot account. Be wary. Check their post history to see if they're real people. If real, leave 'em alone. If empty, use your discretion. Don't ban from related Communities.
Other: Downvotes accidentally when scrolling sometimes. These happen. May appear as a Lurker or a Normal User. Don't ban these or you're the asshole.
Hope that helps!
