My suspicion is that this is mostly happening because platforms that big like google or twitter rely very heavily on machine learning and other AI related technology to ban people. Because honestly, the amount of spam and abuse that are likely happening on these platforms has to be mind boggling high.
So I get why they would try to automate bans.
But after years and years of regular high profile news of false positives, one would think they eventually would change something.
I mean the guy had direct business with Google going on....
Why would they continue like that. Isn't there one single PR person at Google?
