Now that I have said an account cannot be removed, I decided to check the TOS. It looks like my original post was wrong.
According to the current TOS, you can delete your account. Maybe all that a person needs to do is send a feedback and refer to section 13 (c) of the Terms of Service.
"13. TERMINATION You agree that RHP may, under certain circumstances and without prior notice, immediately terminate your RHP account,and access to the Service. Cause for such termination shall include, but not be limited to, (a) breaches or violations of the TOS or other incorporated agreements or guidelines, (b) requests by law enforcement or other government agencies, (c) a request by you (self-initiated account deletions), (d) discontinuance or material modification to the Service (or any part thereof), (e) unexpected technical or security issues or problems, and (f) extended periods of inactivity. Termination of your RHP account includes (a) removal of access to all offerings within the Service, (b) deletion of your password and all related information and content associated with or inside your account (or any part thereof), and (c) barring further use of the Service. Further, you agree that all terminations for cause shall be made in RHP's sole discretion and that RHP shall not be liable to you or any third-party for any termination of your account, any associated email address, or access to the Service."
I assume this would prevent any further access to the account but would still leave the game statistics and old forum posts intact. That would make sense, and would still allow a member to completely remove access to their old account.
Or did I miss something else here?
