- I am denied read-only access to some websites because I use a VPN. This makes no sense at all, but it happens anyway.
- I am not allowed to register in some forums because I use a VPN. Because everyone knows that anyone who uses a VPN is a serious criminal. There is no other option.
- I am subsequently banned from forums because the moderators realise that my IP address is not unique because I use a VPN. My posts don't matter at all, IP addresses obviously unambiguously identify every person on this planet.
- I'm supposed to confirm that I'm not a robot because I use a VPN. The fact that the company asking for these confirmations (usually Google) is itself sending robots marauding through the internet doesn't matter, because Google is Google and I'm just a bloke with a VPN.
Guys, a VPN is self-defence. A website banning VPNs is like a brothel banning condoms. I mean, of course the house rules apply, but I'd like to see a bit more judgement. What's happening right now is ridiculous and hardly does justice to the security aspect of these "tests". If you find yourself as a contributor to this list, I urge you to stop. I am not a bad guy. All I do is use a VPN.
Thank you.
Unfortunately not. The major difference between an honest bot and a regular user is a single text string (the user agent). There's no reason that bots have to be honest though and anyone can modify their user agent. You can go further and use something like Selenium to make your bot appear even more like a regular user including random human-like mouse movements. There are also a plethora of tools to fool captchas now too. It's getting harder by the day to differentiate.
