Post Disappearing..

I would have about 3,150 right about now if all my posts stopped "magically" disappearing. They aren't getting reported because yesterday I lost ~50 in 1 hour. And yet somehow, quality posts are removed and post-whoring isn't. #logic
Why does this keep happening?

Perhaps someone is junking their threads and you must have posted a lot on them.

Yeah, it was happening to me too, no idea why it happens, but it is very frustrating.
