It's not possible to delete your profile, and members can't edit their own posts once they're older than approximately 7 days.
If you can provide links for posts which reveal too much personal information it may be possible for me to remove them but generally, this would be the only case where posts are removed.
The account itself can be banned, if that's what you'd like to happen with it.
You may want to PM me the details, to save further exposure.
