When you post on this site and delete the post is there a copy stored or is it forever gone? Also if it is stored can be accessed my mods or theymos?
Forum admins and moderators have access to deleted posts and topics but there are some more detailed information for you. Those things won't be stored forever with different thresholds for live database, archive database and offline backups.
Deleted posts are at first just hidden from public view. To steal the ID from such a post, the deleted post is given a new ID. The deleted spam post in this case now has ID 57394364.
After about a year, deleted posts are moved off of the live database and into an archive database, and no longer occupy their original message ID in the live database. After about another year, deleted posts are deleted from the archive database as well, though they will probably still exist in offline backups.
The reason i ask is i'm looking for information from one of my past deleted posts.
You can find your deleted post if it belongs to your last 100 posts and it is not more than 7 days old. After each 7 days, posts in draft page will be deleted automatically.
