Maybe that's the next round in the information wars? Each side probing the automated moderating systems of large social media platforms until they find the right sequence that will trigger a shutdown. I'd assume state actors will be able to do this on their own, but for us without state sponsorship, maybe you'll be able to buy it as a service off of the dark web.

Next? Triggering automated bans has been a tactic for quite a long time.

Discord applies automated bans for spamming and API abuse, not for hate speech.

Why wouldn't the probes be automated as well? I would expect some party to eventually unleash hatespeech spambots on the Internet, posting ban-worthy comments anywhere they can reach.

The flood of those comments would both drown out any manual attempts at hatespeech, while also being so unilateral that it wouldn't really make sense to ban any individual community for having them any more.

I love how Neal Stephenson predicted these spam bots in “Fall; or, Dodge In Hell”.

It's not an open platform by any means. 3rd party clients are banned, and what they call "servers" are really just subareas on the company hosted infra that where the broad terms of service are selectively enforced.
