Just went through the site and deleted 82 inactive accounts. Sure, there's a few inactive accounts but they are tied into the RPG manager and cannot be deleted by me using the ACP or Rogue Admin. See here for the list.
For the uninitiated, I DO google email addresses to see if they show up on spamlists. So if you are a spammer make sure get a new email address. Most of the email addresses are automatically flagged by the system anyway before I even investigate.
Have a nice day.
