interestingly enough, it was someone with a different npub that has your same kind0 and the relay set they added has only two relays:
wss://relay.utxo.one
wss://relay.bitcoinpark.com

I wonder if it's because I use blastr via mutiny for my default set...
I was playing around with highlighter a few days ago lining up with these event times, and I did make that relay set with those two relays
