The admins recently decided on a "greatest hits" policy. So, now, only the best of your posts will be shown. It's a win-win for everyone.
Lies. Your post count would have been in single digits I that was the case!!!
As for the op, I have no idea what you're talking about. None of your posts are deleted or anything. You never made 1000s of posts (unless it was using another account, which is against forum rules so chose your next words carefully human...)
