What bittorrent clients may I use?
We've banned many clients for either putting too much load on our tracker or behaving in non-standard ways. These banned clients include Shareaza, Fando, eDonkey (libtorrent), MLdonkey, Transmission, BitComet (and any client based on it such as BitLord) and CFNetwork. Many older versions of Azureus and uTorrent are banned, mostly for announcing too often.
For a full up-to-date list of which clients can and can't be used, see this link.
Some Windows clients we recommend:
Azureus (Full-featured; portable; provides very reliable statistics to the tracker.)
uTorrent (Highly Recommended. Uses very little system resources.)
Clients in alpha or beta version should be avoided.
For more information to assist in selecting a BitTorrent client, see: Comparison of BitTorrent clients at Wikipedia.
Most common reason for stats not updating
The user is cheating. (a.k.a. "Summary Ban")
The server is overloaded and unresponsive. Just try to keep the session open until the server responds again. (Flooding the server with consecutive manual updates is not recommended.)
You are using a faulty client. If you want to use an experimental or CVS version you do it at your own risk.
Best practices
If a torrent you are currently leeching/seeding is not listed on your profile, just wait or force a manual update.
Make sure you exit your client properly, so that the tracker receives "event=completed".
If the tracker is down, do not stop seeding. As long as the tracker is back up before you exit the client the stats should update properly.
