They're probably too connected to the other posts in a thread....but an Admin will know better than I.
when threads you started get deleted, not only your posts get deleted but every one who Responded Loses posts Too.
If you mean why don't we delete accounts and posts, it is because it leaves huge holes in many threads. If we delete a post do we also delete another member's quote of that post the member want's deleted since it is quoted. If a member only has a couple of posts it isn't a big deal if they have hundreds or thousands then deleting them will leave huge holes in many threads destroying them and members who don't want their posts deleted still lose posts since the thread was deleted that had their responses and many times important information to many other members..
