I may be dumb, but why does reddit have long chains of deleted comments? - Lemmy.world

Why does reddit often have at least 1 semi long thread with all of the posts deleted?

Also I could add many who are leaving reddit have deleted their accounts and all content they posted. Not sure if that’s the case here but maybe?
Its a reasonable theory. altho it sounds like it would create partially to mostly deleted comment chains and only occasionally fully deleted ones. (Im not on reddit anymore and have npt looked at their comment sections lately. If i missed somthing, let me know)
