I do see it as a potential problem with moderation on Lemmy's end. You have all of the users from Threads interacting with Lemmy and Kbin users. It's possible there's an influx of accounts on here that are trolling, and it becomes unmanageable to moderate everything on Lemmy's side.
But Threads will have no problems with content moderation.
