How do I delete an account I have that is sending out offensive emails?

 I have tried multiple times to reset the password and I get the following message everytime. "You've reached the limit for account recovery requests" Even when I get a new code, the thing goes in a loop, never letting me in the account., and giving the same message,  How do I delete an account that is sending out bad emails?.

I just want to delete the account so this all stops. password recovery doesnt work either. HELP!!!

Thanks
