Well here’s an issue with Threads adding ActivityPub support that I hadn’t thought about:

As Threads removes spammers and other bad actors, they will attempt to evade the bans by setting up new accounts on other Fediverse servers, in the hopes they can still reach Threads’ tens of millions of active useres. For Fediverse servers, that could mean an explosion of new adversarial accounts that few are prepared for.
