I can hit the 'spam clean' button on your account, and that'll not only close it, it'll put you on a list to ensure you're not able to get back in - as well as potentially hinder your ability to join other forums that use the same defensive software. It's a drastic measure, but it can be done!
The admin here can delete your account, but they're exceptionally busy lately. It's harmless if you leave the account open. Your information won't be sold, traded, or given away.
