First, is the marketplace at torrentinvites.org legit? Second, is it dishonorable to do such things? Third, how to avoid scams? Fourth, are there alternative marketplaces to have a sense of whether the price is right?
UPDATE I wanted to thank all for the feedback, you made me change my mind and saved my ass from some costly frustrations… good thing I asked here first!
The best trackers have some pretty strict rules regarding IP-addresses for this exact reason. If you’re suddenly browsing the site from a completely different location, it could raise flags. If you’re moving country or using a server/VPN (for browsing, not downloading), you might need to notify staff about it.
But as a general rule, if someone claims to sell invites to the top-level trackers it’s probably bullshit anyway. They are very closed down.
