> "artificially" amplifying information Isn't that the whole point of Twitter?
I think what they meant was that they detected bot activity associated with the account.
1) Every account on Twitter has "bot activity associated with this account": if for no other reason that random advertising bots retweet, follow, or like random people and posts to attempt to blend in as a genuine account and hide their true purpose. This reasoning gives Twitter essentially carte blanche to delete everybody, even assuming they were willing to be fully transparent about the evidence surrounding their bans (which they're not).
2) Bad Actors can easily sabotage accounts they dislike. Here's just 1 method how this can be done: there's 10,001 shady fly by night firms in India, Pakistan, Nigeria, Bangladesh, Vietnam, and other countries that offer services to "buy followers" or "buy retweets". It's trivial for somebody without programming skill and even a few hundred dollars to just buy mass spam and shill the hell out of an account (the lower quality the better) until somebody notices and that account gets banned.
You don't even have to assign bad motives to Twitter to see the obvious problems here.
