Your choice of words there is uncharitable. I don't know why you did that by calling those who do it "foolish". I wouldn't call anyone who's making a legitimate hustle and earning from it foolish, even if I don't like what they're doing. I've profited from some of these tap2earn you classed as foolish and will still earn from more to come. Your advice should've been that those who indulge them should do their own research (DYOR) and be careful, not that they're foolish.
