Hmm. Suppose I want to buy a bike. Joe steals a bike and sells it to me for cheap. I did nothing wrong, but could be forced to return the bike. But if I resell the bike, I am no longer liable?
It's more like what happens if someone steals a bike and while riding around on it sees a billboard which leads to profit for the advertiser. Are you saying the advertiser now owes the bike owner something?
