You do realise that not all DT members are moderators right? Moderators are directly appointed by Theymos. There is not way to be "voted" in as a moderator like their is with DT(2).

If your posts are being deleted by a moderator, then you are more than likely breaking one of the posting rules (multiple posts in a row/off topic/trolling etc). I've had plenty of my posts deleted over the years don't take it personally.

If you have posted in a self-moderated thread, the thread creator is free to delete posts as they see fit...
