Block lemmy instance.

Not on Lemmy yet, but here's how to do it on kbin:

https://kbin.social/d/[domain here]

Block button will be on the right next to the subscribe button (which is another cool way to grab everything from a particular instance).

Example:

https://kbin.social/d/lemmy.world

Nevermind that, is there a way to block any post with 'AI' in the title?

Not currently. You have to individually block the top communities from that instance.

💀

apparently you can via kbin
