I have noticed that a non insignificant amount of seeders, particularly when downloading hot torrents with tens or hundreds of seeders, will just be connected but sending no data. Is there something I can do to fix this if this is an issue on my end? I assume it is just their bandwidth maxing out or something like that but they are taking up connections for no reason. Is there a way to make tixati disconnect from a seeder if they haven't sent X amount of data in Y amount of time?

I have noticed the same when using Tixati. This is very easy to see on a hot torrent as you said. For me it is either a very slow ramp up to max speed or never reaching the max speed.
