This is a terrible idea & will create more spam & in result because I keep seeing the same noteore then twice I like many others would end up blocking every single person sharing the note.

Spam is already an issue that the filter to me personally has no use. I still see the same jap or chinese doosoo chatgpt yadayada with the filter on. I can see spam makers using your idea to zap their own spam boosted & share the zaps mostly to themselves which would encourage more ppl to do it. They will think hey zaps for me if I share & boost then it will be a clusterfuck of boosted spam non-stop all day every relay. Then i'll have to quit nostr.
