I'd just like to know, what is the deal with trackers that demand you use an older version of uTorrent and reject people using the latest version of uTorrent? I think users should be able to use whatever torrent client they want, and whatever version of it they want, and not be discriminated against by trackers. Some of these private trackers have very long and bizarre lists of rules, with their lists of supported clients (they use whitelists, not blacklists) not making much logical sense at all. And each one has a different list of supported clients. So if you want a bittorrent client that works with all of the private trackers out there, too bad, there isn't ANY client that is on all of their whitelists. This also discriminates against users of less-well-known torrent clients, such as the many open-source torrent clients out there, many of which are not well-known enough or too new to be added to the whitelists (for instance Tixati is on hardly any whitelists yet, although most of them do include Deluge, qBittorrent, and Transmission, along with older versions of uTorrent and a couple other clients). I don't see any legitimate reason people should have to use an older, outdated version of a program, especially since older versions might have unpatched security flaws. I guess the newer versions of uTorrent have so many features allowing users to manage their upload and download speeds, maybe the private trackers don't want anyone with those features because they are worried someone might set their upload speed to something slow. But this is not a legitimate reason to block newer versions of uTorrent, those trackers have many other ways they can prevent leeching and monitor people's upload:download ratio. If people want to use an older version out of personal preference, this is OK, but it should not be forced on people by bittorrent trackers.
