Most of the time when one of my post's is deleted, it's because I either posted in the wrong forum, posted on a topic that was already posted and beat to death or I didn't follow the forum rules for posting. Rarely do I have a post deleted simply because I'm fat and ugly.
From what I see you have posted 6 times since joining and they are still there but may have been moved to the correct forum. Most are in the CR,YZ etc forum and one is in the product review. There is also the chance that they may fall off page 1 if no one responds and other posts superceded it
If you post in the wrong forum more often then not it gets deleted we just don't have time to move threads around.
