I just posted the proof. I'm not saying the default settings will harm the network, but this client is aimed towards advanced users, it seems. Many of these people will be tweaking the settings to their advantage, in turn hurting the network. Have you ever seen a Qtrax2 user hammer you for files once per second? Even while they're already downloading the file from you? I never downloaded Qtrax (I did download Shareaza and give it a spin), but I don't think those are it's default settings, either. But the fact is, alot of people who will be downloading this will set it up so that it best benefits them, without regard for the rest of the network, as we've already seen with Qtrax. And I believe this client has the ability to be even worse than Qtrax on the network (more options for the tweaking, and no limits to what they can set them to).
