To be clear, it makes sense to ban fake accounts proporting to be well known people and people breaking the law.
Banning anyone with views you dislike and anyone paroding conservatives is where it gets censourous.
Thanks for the link but nothing in that article supports this comment. The only mention of content not allowed is:
1. Matze's post about spam, NSFW content, and death threats not being allowed (https://www.cato.org/sites/cato.org/files/styles/pubs/public...)
and
2. Matze's post about banning the accounts of a group of ANTIFA supporters (https://imgur.com/WaAMEyn). This image was linked without any context (perhaps because Matze posted this without any context) so we don't know why these accounts were banned.
