In 2020 when the lockdown stuff just began, my 10 year old account fell victim to one of Facebook's new mass purges, which I had never heard of before in the company's history - then I experienced it. This must have been preemptive because the anti-scamdemic crusade wasn't being waged by any or many of us yet.
My partner turned around to me one day and asked if i had blocked him on facebook, I said "no, why?", and he said my profile and messages and all data had straight up disappeared. I checked my account and and it looked like I had been logged out with no trace of login details... it got weirder, every trace of my account had been purged, down to every single message I had ever exchanged with friends and any mention of me there had ever been.
In the end I had to create a new account, I lost some data that I really wish I could get back, but ultimately they done me a favour anyway, erasing 10 years of "hate speech" and thought crimes for me, lol.
During 2020 & 2021 I created numerous other accounts to disseminate Hunter BIden leaks and I was repeatedly banned mercilessly, but for some some reason they allowed me to keep my main account, and they just ban me the regular way on there (warnings, ghost bans, reduced visibility etc), almost like they know they are playing a mind game with us all and don't actually want us all to leave, instead they are trying to correct our thoughts and behaviour.
The Hunter Biden Facebook wars were pretty epic as people were trying to game the AI censorship whilst it adapted with each new round of meme warfare.
