I can quite easily imagine HoneyGain clients using my connection to look up illegal stuff that would get me in trouble. Plus, I'm quite sure this kind of thing violates the TOS for most internet service providers and would get my service disconnected.
@Gulfie Yeah. Also reminds me of some old "work from home" scams, where you were getting paid to just mail stuff on behalf of other people, and this was really a thing crime orgs were doing to hide their tracks and create a scapegoat.
@Zauberin yeah it sounds like Tor but worse based on your description
