Thank you for reminding me about this. Next to soulseek I'm going to use it to not obey!
Didn't soulseek had some requirements you had to fulfill before downloading?
I've used soulseek pretty recently! There's a nice client called nicotine, IIRC.
There are message bots that spam you with racist abuse if you're sharing nothing (i.e. not even your downloads), but that's about it.
Oh so pretty much the "classic" share something rule; that was pain in the ass in DC++ times but quality of whatever you could find there was best
DC++ now that's some nostalgia.
Myself used IRC XDCC bots connected to my 33k modem connected to my 486DX which would disconnect every three hours.
eDonkey, WinMX, lovely fashionable protocols.
Not to forget the eMule.
