You may have turned on the VPN when you visited a website where your IP address is blocked or didn't want to be discovered, and forgot to turn off the VPN when you switched to Wikipedia, and Wikipedia reacted toxicly.
Yes. If you are banned and you are evading that ban with a VPN, you are, obviously, ban evading. That's what that means.
Well, if I don't use software, it isn't VPN right, and I don't think I have ever been banned anyplace, but I have banned a person that never edited on a wiki, so it could have happened to me as well and I never know about it. Anyway, needless to say I'm old and forgetful, so there are a few accounts I forgot about over the last decade.
