The stuffs of tracker Redacted Gazzelegames etc investigates all user who are invited to their site. They first disables the invitee account and then they asking lots of proofs like inviter details and conversation proof between inviter and invitee in inviting time. They behaves so poor and ultimately they disables those who are involved in trade, and using inviting sites. So be careful and try to send invites as ownway to those trackers.
