Agreed with Vespian, we are human. I apologize if my message did not get through to you, or if your message got flooded away in my inbox (this does happen, after all, and staff members receive messages from users each day), but that's hardly reason to believe the staff do not care. It's appalling that you'd jump to such a conclusion, but to each their own opinion.
Adding onto this, we do not actually delete any accounts unless there is a very real need. Your emails will be secure, as deleting your forum accounts has already been done on your own, and the game connection will not be sending any emails to you. The information is safe, and will not be touched by FH or any third parties.
Just as well, if you don't log into these accounts for some time, the server will automatically begin to clean out inactive accounts on its own. Routine maintenance. So your accounts will be deleted in due time if you do not access them.
