Instead of DELETING members that violate Terms of Service, etc, it's more important to "BAN" them.
All I would need is their Username, IP Address (admins/moderators can see this), or an email address of the suspected member.
Deleting an account, removes member information from the database. So the person can RE-USE the email address to register for an account.
Banning a member will make it impossible for the person to use the email address again.

I will never surrender of my own free will. If in command I will never surrender my men while they still have the means to resist.
