If "some jerk" deletes my post, it wastes my time, and will cause me to reply less in the future (to everyone else too), that's the "chilling effect" I was thinking about.

Ultimately, I think the poster/replier should own their own notes (undeletable), that's like a basic principle of nostr.

I tend to agree with nostr:nprofile1qqs2qzx779ted7af5rt04vzw3l2hpzfgtk0a2pw6t2plaz4d2734vngpzamhxue69uhhyetvv9ujumn0wd68ytnzv9hxgtcppemhxue69uhkummn9ekx7mp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7hycrvd that reports (kind 1984) seem to be the best way to do this. I can reply to you, and you can tag my reply as low value/spam, and other readers (or their clients) can decide for themselves.
