I've been permanently banned from countless imageboards, international, single language, tor only etc. Countless of times, with the aid of multiple, free and paid anonymizing services + router resets I've evaded probably hundreds of said bans and I've continued my posting openly boasting and announcing that their actions were useless and only emboldened me and inflated my ego, until the admins and mods' hands were forced and had to resort to blanket ban Tor and any VPN or proxy service, at times even blacklisting any anonymizer from accessing the site entirely, and my public IP range whole.
I've caused numerous word filters and image hash filters to be implemented site wide to try and combat me, I've been accused of being numerous different literally who locals despite not even knowing whom they were and I've entertained both the admins and the people who accused me for the sake of making them run in circles.
That is to say I didn't do it because just for the sake of it.
All I've been doing is fighting against injustice as the vast majority of the bans were for frivolous, vague or downright made up reasons like pointing out moderation flaws, "spam" and other similar things. Of course, if I deem something unjust, I'm simply not just going to take it like a good boy, I just wouldn't. I would not let my voice be silenced. And thus I fought fire with fire. I became what I was being accused and drove them to their own self destruction. I trolled, I derailed, I spammed, I acted like their bogeymen and everything they expected me to until I was forced out of ways to post at all. Many imageboards shot themselves in the foot and forsake the true anonymity of their users just to get rid of me.
On the flip side of the coin, more the once have I had to deal with people like me as both an admin and a moderator. Although their motives might've been different, the method of operation was practically the same as my own. The existence of anonymizing services means it boils down to who chooses to spend more time actively fighting the other, be it by spamming or deleting, until the moderating party gives up and just blacklists said services.
The moral of the story is much like all humans are fallible, all mods and admins are inherently cucked by default whether they like it or not, some can keep up a front for more time than others but in the end no one wants to spend 12 hours a day, 365 days a year in front of a computer actively fighting an autist to delete their shit on sight and not get paid to do so. Everyone has a breaking point and it's just a matter of someone like me racing towards it to reach it to permanently cripple a community by collateral damage.
The moral of the story is hosting and managing an imageboard is a fool's errand, as it's done at a loss of time and money and all you get in return is stress, scorn, ridicule, mockery and constant attacks from the very same users you're offering a free service to.
