A dedicated hater would just open a new account to annoy you tho. It takes 2 seconds to make an alt.
Discussion
But I do like the thinking.
I think this would make more sense on a different use case outside of microblogging. Like a substack clone or something. Set comments to 21sats, that way even a hater would have to pay to comment on an article, would probably reduce that sort of thing 99%
Supporters/subscribers who already pay can comment for free, and non-subscribers who want to comment would be happy to pay. Haters would have to pay, so their annoying comments are at least an earning
Web of Trust
Would web of trust be a thing in the substack/subscriber format?
WOT might have specific meaning here in Nostrverse while I realised I used it rather broadly
However this could work as follows. If someone is a subscriber then they comment for free (they already paid) and randos have to pay. Now let's say a subscriber follows someone and then that person can comment for half price
This would make following others mean more and complicate things because we follow others for lolz sometimes and it would enable them. We do not want this. A well-designed system of lists like Bluesky has or Twitter had could allow following others without building their reputation
But this sort of platform like substack a content creator may follow no-one or like 5 /10 /20 other content creators on there. It's not like microblogging. so not sure there's much of a web
