One of my new trackers has banned Tixati because, according to them, you can cheat with it and thus alter the upload rates sent to the tracker—just like Ratiomaster can do.


That’s crazy. Honestly, I know Tixati pretty well since I’ve been using it for years, and I’ve never seen that option, but maybe it’s just well hidden.


So, myth or not—can anyone shed some light on this for me?

Tixati doesn't have an option to change reported upload. However, people can fake their upload stats easily with any torrent client by seeding to themselves without using RatioMaster or similar programs. Of course this kind of cheating is usually not hard to detect by the site staff members.
Anyway, If you want to bypass Tixati ban see this:
