I think there is no more notificition. Last year -I guess- there were some notifications. But now , moderators just delete the posts/threads.1-2 months ago, I posted a post on a thread deleted a little after. And I didnt get a notification.
So they've removed the notifications about that? That's actually not a good thing if you ask me. Those notifications were quite welcome for me.
Maybe a thread that you posted in was moved to the trashcan. You don't receive a PM if a topic is moved there.
Posts that were made in threads that get moved get deducted from the total post count?
I have no idea if anything was moved.
