And as the reported stats originate from the torrent client... They're able to report whatever they want.
I remember using some obscure tool before 2010 to intercept these packages and update them.
I was in my early teens back then and used it to overreport my upload statistics by something like x2 on some private trackers, so they wouldn't ban me.
It used to be easy to falsify that information, but no more. Most private trackers would easily ban you for that nowadays, unless you can get all the other clients to also cheat with you using the same parameters. It's easy to cross-reference the information coming from N clients, so you'll be booted relatively quickly.
That sounds like a useful development to counter such abuse, but i don't think this feature helps your torrent client wherever it should upload data to any given peer.
