Market incentives can work on a broad scale (SN disincentivizes posting ai slop) AND individuals can miscalculate the cost/benefit of such behavior and think it makes sense (and sats).

The hope is that on aggregate, this leads to less slop. However, there may be other factors we aren't taking into account.

It's kinda like coupon clipping. You might feel like you are saving money, but in most cases it is probably costing you more in time and effort than it is worth. After all, stores offer coupons because it is good ROI for them, not necessarily for you. And yet lots of us still spend time clipping coupons, because it feels good or it's what we think we should do.

Same as the house always wins, but casinos are usually full of people. Some people don't mind losing in the long run in order to win in the short term.

I don't think the people who post slop enjoy it, but it is a possibility.
