The very short answer is:
We get flooded with shitty clients daily, there is ~8,000 torrent downloads daily, about 50% of them are illegitimate. Illegitimate being these clients do not seed back - at all.
I use Vuze Btc and what is wrong with that? Worked perfectly fine for manny years and has no adds, is free and seeds as much(or little) as I want or can with my band with. Yet it is"wrong"? Why should I have to change just for this one source, no other has complained before? Making all f95 users switch to your "approved clients"or be left out of using torrents is not cool.One wonders if you are getting paid from them perhaps?
