I don't think anything wrong happened here.
There were so many bots listening to that address at every moment, and not even one tried to replace the transaction ? I doubt it, if so then the person who sent those sats is mocking us..... I interpreted "you're so dumb, what were you thinking and you deserve nothing" as what were you thinking trying to send out the coins through the mempool(exposing the public key), you're so dumb, the coins have been stolen from you, you deserve nothing OR mocking us, what were you thinking playing a losing game, you're so dumb, you deserve nothing.
Can sender of microsat know of balace move faster then others because this microsathoshi ?
