i'm of the impression you should ignore them, that's the logic i have, you get these kind of comments on youtube all the time and that's not even for money, it's some kind of psychological problem people have, it's all human nature and psychological . i've not got a clue if flagging them will make much difference, might just frustrate them, causing them to be a danger to humanity in another way, because they may not understand why it's happening and someone who does not understand anything, may end up being a danger to the people around them, by harming their mental capacity due to being in poverty. you could be flagging a high level risk, therefore maybe they should consider if the man is mentally stable enough to be flagged.
