I guess on something like BCG it wouldn't be too necessary. That's a good point. It is for, well, games :lol:.
But for sites like PTN, bitme, ftn, ftwr, fsc or any other tracker that has weird content (like bitme) or is "community" based (like FSC), not all people really want to join the community. They just go "zomg its rare must be good cause its lvl 10 in wtaw". If they actually looked at a guest account and see that it's serves a completely different purpose (doesn't necessarily mean its bad) than say TL or SCT, they may change their mind instead of trying to trade to get it, or collecting it than leaving it mostly inactive.
As for your other point, guest accounts could be public (or just put on the homepage of the site). Members could just tell potential invitees the details (or they might be leaked out, but as I said before I don't really think that'll compromise the tracker).
As to your "PS", whether its mocking or not, I'd much rather post at FST than in a tracker forum. I just like it better. It's more open, anyone can post in response to me, and you don't have to worry about being banned by anyone, so theres no asskissing. Just straight, to the point voicing of your deepest, darkest opinions
