There's certainly some wash zapping on Nostr. You can do your own zap forensics by going to the Explore section on Primal, then selecting "Zapped" in the Global category. That will give you the most zapped list of all time. Some look legit, some don't.

Okay cool, I see #[3] has the most zapped note of all time, but it seems he was doing an experiment of sorts… classic Semi
On the subject of "zap washing" there is someone that posted a picture of how much they zapped from somewhere. And I noticed that they had zapped themselves many times in their profile. Made me really uncomfortable. See him every day on Nostr, always talking about zaps.
