So you have posts disappear, when you have the same number of posts? I can think of a couple reasons.
1) You posted in the Newcomer's forum and/or the Forum Games forum and had posted deleted from there. You noticed it, but it hasn't affected your score since they don't give out AP for posting.
2) You posted in certain threads which don't load the page correctly. Those replies of yours are still there, but the page was incorrectly loaded and only displays part of the whole responses. This happened to me about 2 days ago. A thread with 4 replies, including mine, would instead only have 1 reply, but when I reloaded, the entire page would show up. I would try to reload the page if this is the case.
The other case is if mods or admins are removing posts that don't follow our Rules and Guidelines or Terms and Conditions, though we'll pretty much always tell you why we're removing your comments.
