Okay, let's separate this into the troll / steal arguments.
Troll - am I a troll for proclaiming the truth and calling people idiots when they blindly and naively keep dumping money into trying to mine crap coins that have no future? I speak the truth. I may have no diplomacy and I may offend people in my way of addressing these matters, but I'm not wrong in my assertions about the coins!
Steal - is it really? If someone calls me to work on their computer, and they didn't know there was a bitcoin wallet on it, or they did know and thought it was useless, then I am not stealing, I am merely capitalizing on their ignorance for my own personal profit. Somehow, I think that sounds better than "stealing". So far I have not found any Bitcoin wallets, and I do check the appdata folders on every PC I get called to look at.
If I didn't save those coins and put them back in circulation, the computer likely would eventually be turned off and thrown away with those coins still on it. And if I can make a little profit on the side, then what the hell, why not?
