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!
Yeah like others mentioned, I would strongly advise against doing this. Will probably get scammed or cabal banned at worst too.
But my advice if you have the money to spend and want to just easy access, look at the donation signups that Brickfrog mentioned.
In particular, I think TL, PHD, HDT, AvistaZ, and CinemaZ are worth while to donate and join.
