To add to this, we get about 50 memberships requests a day. Most of these are bogus, people who want to get in so they can spam us for Viagra or some other bullshit!
I try to filter these out as much as possible, but sometimes one gets through. If somebody spams us, I remove it as soon as I see it, and delete their membership.
If anyone who is legit gets denied, have them send me an email. When they register, they get sent an email to let them know they are being considered, so they have an address to reply to.
Thanks,
