Can't create acct from Tor browser?




I have a friend who wants to join but he's big into privacy and wants to use Tor. He emailed me saying when he tries to create his acct he gets the following message:

"Your email address or username or IP address is blacklisted. If you think we made a mistake then contact us at"

He's tried using two different email domains. He also says:

"I sent a message to the MuscleGurus admins from the contacts page, but didn't receive a reply"

Anyone know about this issue?
