Almost all moderation is handled privately to avoid embarrassing forum members. Reminders and warnings are sent by Private Messages so only you and the moderators see them. When reminders and warnings are listed on your User Profile, only you see them there; other users do not see them. The moderators keep records of their actions so administrators can review the messages, but these records are not shared with other users.
In keeping with this privacy policy, if you post in the forums asking why your post was moderated, your post will be removed (it's almost always off-topic to the thread it's in). The answer to "Why was my post deleted?" is always the same: it violated a forum rule or was a quote of a post that violated a forum rule. If you want a further explanation use the Contact form so we can be perfectly frank and discuss your posts and forum record. You can post in the Site and Forum Feedback forum if you want to discuss forum rules and moderation policies in general, but keep it general, not about a specific case of moderation.
