We don't report accounts to advertisers. The unique account number is generated by our system and it's just a number, nothing personally identifiable about it. Everything submitted, we have the rights to keep on the site. We remove content as a courtesy if there's a request, but in light of the fact that content is requoted and deleting all posts of a member would not delete those quotes, it's not really wiping out an account completely just by deleting all of its posts. Having said that we've deleted many threads on request of the poster who had some reason to want it off the internet and will continue to do that as a service to members.
Usually when people ask for account deletion they want to stop getting email notices.
