found it complicated and unpleasant and downzapped it lightly

Me too, and:

click on details to see how much it has been boosted

I missed this the first time around on the first post, because I just downzapped it with the default zap and then it was gone from my custom view (I do have a way to force it back into my list tho, which I did when I saw my satistics going bananas.) So this is a point of friction, but as you say:

But wed probably also see a lot of new negative behaviors as well.

@k00b convinced me of this earlier this year: too prominent negativity invites more negativity. So I can personally live with the 2 extra clicks to find out, and 2 extra clicks to downzap.

If there was an easy one-click downzap method

After the first downzap there is such a thing (well, 2-click really), but honestly that's the time when I like it least. To me personally, zapwars are wasteful, as in they waste both energy and sats, so I am in fact much aligned with @siggy47's opinion both here and in the prior thread. I am arguing for something I really hate doing, because I hate scammers even more - it's 2 evils for me.
