mid tier trackers partner with seedbox providers who give them kickbacks for referrals, in exchange for an account
It's probably easier to lurk in r/trackerinvites (or whatever it's called) hoping to snatch an invite
I think it's much easier to pay 12 bucks for a month of seedbox that includes an invite to TL, than to hit F5 on /r/OpenSignups for months/years until they open registration.
Yes, it's probably easier. My quick search revealed no such seedboxes.
