Please be aware that Azureus/Vuze clients are henceforth blacklisted.
I'm sure you have seen other tracker doing similarly, and our reasons are identical to theirs. Azureus/Vuze has a plugin system which makes it all too easy to cheat our tracker and abuse the carat system. In order to preserve the overall health of the site, it has been blacklisted. This will only affect a minority of users, and we are happy to be able to recommend a number of alternative clients.
Thank you for your cooperation.
