I think it would be better if one would be able to see what kind of torrents are on a given tracker before going through the hassel of finding an invite. I mean, whats the point of joining a private tracker if none of the torrents are of any interest, or even found elsewhere with a bigger swarm?
So if a potential new user visits a private tracker and can't see whats available, or perhaps is looking for only a very specific title and nothing else, why not have some kind of quasi-limited account which is only active for a time period of say, 24 hours, after which the account is locked for a time of 30 days or so?
I think the idea has more advantages than complications.
As far as abuse is concerned, any tracker, whether public or private is going to be subject to the same sneak-in attempts by police or other anti-piracy agencies, which they all have accounts on the trackers anyway.
Leeches and hit-and-runners could be monitored by bots, and auto banned or throttled tracker side.
I personally don't want to keep track of each torrent site to make sure my account is still active because I needed one file from said tracker once upon a time.
Any constructive comments or thoughts on this from the forum?
