I tried to find one such note; but sadly couldn't. I did read through ~100 of this. xD
Untill I spotted the outlier.
# nak -q req -l 10 wss://nos.lol | jq ".kind"
30000 <-- Follow set
7 <-- Reaction
10000 <-- Mute list
7 <-- Reaction
1 <-- note
1 <-- note
9735 <-- zap
7 <-- reaction
10012 <-- ?
7 <-- reaction
10012 is not in the NIPs kind table, so let's try that one.
# nak -q req -l 10 -k 10012 wss://nos.lol
{"id":"ee52e2737c8745c6e03fc86f4b94ffc09d9398cf0ca9d7c1c3daf084fb0ab97d","pubkey":"b89fec72c59158930fe9d5b93562189c72bc085c5970f66d8d9d82420650f165","created_at":1706592089,"kind":10012,"tags":[],"content":"This is a relay test on 1706592089.6246736","sig":"618fe9452a2a5bcf37bcdc4d5c49c3b008b53ba9c5021bd73d786a730e589a18d5baebd9b248e01ac9f2ce20a2ca3b8f02abe3cf9bd45caa3f67e2d085744715"}
Success!
