As a young troublemaker I was banned off of a Christian youth forum for linking to divine-interventions.com.
I got kicked out of a random Facebook group that I really had no business being in in the first place when someone got very offended over the phrase white girl wasted. She had built up a full head of steam so I called her a nigger to see what would happen and what happened was I got banned.
Also lolcow.farm accused me of being a guy a few months ago and I have no idea what the hell was even going on.
Got banned off multiple Minecraft Pocket Edition servers.
-one time was because i called out a server owner who allowed a this guy who both of us hate each other. I said all the shitty stuff he done and was banned. I went on a random name i created instead, re joined the server and secretly went up the ranks to unban myself. They never noticed...
-Another server because the server owner was stream advertising on a few streams and i went to complain firstly about that and secondly about the spawn which wasn't that nice.
There are a few others but i don't want to get into them since they all somehow link up to my first point.
Only Canada, the couple of times I was banned for bullshit reasons on SA by the catladies (and mccain) doesn't count, I took it to Fragmaster who after some arguing always went "urgh, fine" and I didn't have to buy a new account. He seemed fairly reasonable but that might be because the mods and other admins were insane.
Banned from a forum for calling out a poster's suicide baiting and not giving him asspats, and telling him that people like him do a great disservice to people that actually are suicidal or depressed and not m.ilking it for attention.
Banned from a store for shoplifting when I was a teen.
I lost 7-8 Twitch accounts for making fun of 16-bit. He was a pro Mortal Kombat player for a long time, got hired by NRS, then lost a lot of weight and became a low effort tranny. Most of the bans were for dead naming, but the last couple came from spamming "STUNNING AND BRAVE." The funniest part to me is that I met him before he transitioned, and he has made zero effort to change his voice.
Got perma IP banned from all 4chan boards for telling an anon to dump Daisy's Destruction in the hope that he gets arrested.
Got banned from a gaming site for posting live farmstock killing.
Got banned from TVTropes for calling Fighteer a dick sucking monkey.
Got banned from GameFAQs for saying that the Jews were behind the failure of the Wii U.
Got banned from some forums for shitposting.
Got permanently banned from Facebook for making an Amanda Todd joke right after she killed herself.
Got banned from a Discord server for shitposting about how waifufags and lolicons deserve death
Got banned from another Discord server for constant shitposting
Got banned from a Doom server by Spanish speakers for speaking English in an English speaking server.
Got banned from a Pokemon Online server for pissing everyone off, posting hentai, antagonizing others, dropping racial slurs a mile a minute, all while having the power to ban pretty much anyone I wanted to, including the server owners.
All those bans are no longer in effect because I changed IP addresses.
EDIT: I forgot to mention the ban on a third Discord server I got after saying that blacks shouldn't get statues because they sold slaves in a history pissing match.
Uh, banned from one forum when I was like 10 for role playing three characters at once.
I can't remember every ban from 4chan, but my most recent was for trolling the mods over banning threads about ProJared's return video. Kicked out of a couple facebook groups, one was D&D related cause I was making fun of D&D 3.X fans.
Banned myself from an autistic group because I was one of several admins and the big dick on the block had a shadow war with me trying to defame me.
Haven't been banned on KF's yet. Had a report get laughed at once and posted something horrifying on Null's page.
