HD-Torrents and Sportscult have the same owner
This is just FYI, nothing more.
Some may have noticed similar invite and pay2register practices on both sites.
Sportscult is currently offering the same type of "temporary" invites to their members that HD-Torrents often offers.
> sportscult.org is in free invitation mode. sportscult.org give you 3 free invitations to invite your friends from here.
You'll notice the announcement has the same type of poor English often seen on HD-Torrents.
