Sadly there’s disproportionate value. Your attention is only worth a few cents, the criminals (SEOers, scammer ps etc) is tiny per user, but the cost to you of the misinformation and wasted time is larger.

Like breaking a shop window to steal something small and easily transported/resold.

I think this is why there is value in moderated spaces like reddit [complex feelings here], the moderators and team/tribe mentality ensure that there is informational value to at least that group [more complex feelings here].
