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?
There are alternatives to all these: Search, Email, Game streaming, Online doc editing, Etc
It works for you (as in, single person). Not for your friends and family who will ask you one day what to do about the account they lost.
We (technical people) know this happens and have seen it happen - it is on us to push for better solution than convincing one person at a time. Unless one prefers nihilism and watching the world burn of course.
