Why is it so difficult to get torrent invitations?

You can mostly buy invites for a very small fee, so I don't see why ppl have to beg for invites.

I'm not sure what sites these people are members at, but no REPUTABLE private tracker sells invites other than IP Torrents. The whole point of invites an exclusivity is to keep people like you out. Go join some lower tier private sites build your ratio and get to higher user classes. A lot of sites offer invites to reputable members of other sites!

I can tell you begging / asking / trolling is not the way to get it since all of the top tier torrent sites SPECIFICALLY ban giving out invites on forums/ in public
