This has been gone over many times,nobody can delete their account,the admins have said many times the reason they dont do account deletions,the reason was that every time some kids mom is on to them or any other reason people panic & get sketched out they want account deletion,they'd be deleting hundreds of accounts daily.
It aint gonna happen,if your not happy here all you can do is leave & never come back,or try to fix the things you hate about the site,either way its all you got because admins or mods cant & wont delete any accounts for any reason.
