Yeah, I'll second that .
I've posted several times asking moderators to check mine and see whether I'm real or not. I even posted a link to an app where people can check it for themselves, because I walked into a forum which I like, but in which I've been continuously accused of being someone else , which I'm simply not.

The only thing is though that you might get different members of a family with the same IP address, so maybe just note that against the account on profile rather than banning them.
