Interesting. My initial thought was that botting on the fediverse might be easier than on a centralized site, since you can target your bots to several instances at a time. If one of them catches on, your bots can still function because they aren't being banned across all instances.

What you say about being able to quarantine and cut off instances that are being spammed makes a lot of sense though. I'm glad that at the least there'll be some new challenges for bot authors.

Ultimately though, the relatively small size of the communities is our best defense against bots at this point. Lemmy/kbin just aren't great targets yet because bots won't reach enough people to achieve their creator's goals.
