There is a way to detect ratiomaster etc.
The emulation from my research is not clear cut. The client reports the spoofed client in the announce report so banning a legit client/agent would occur and effect users not cheating. Correct me if I'm wrong. For example..
In an announce report string a users peer id was reported as TR2920-qjrjul0060o8 which is Transmission/2.92 however this user spoofed his reported upload amount using ratiomaster and the only way to tell was by checking the snatched list completed dates for all snatches on the torrent his announce reported which were 4 weeks prior to his announce report.
In theory the solution imo is to initiate a server side handshake and analyse the response as client to client does no anti cheat checks regarding handshakes, the response could be analysed server side and give indications of a cheating clients response or non response. How this can be achieved involves using the bittorrent protocol in order to code up a server side handshake.
Thoughts?
