Scammed by InkSource for Torrent Invite

[crispychris]

What happened::
I tried to buy a torrent invite from InkSource. After I paid, he never replied and refuses to reply. His topic is self-moderated so any accusations on his thread gets deleted.

Additional Notes:
I've tried to get in contact with him but it's impossible especially with his self-moderated topic.
Worse is that he's flooded the "Invites & Accounts" subforum with other self-moderated topics to scam others:
