my key was mined at the other end to make a 5 letter word same as my username... i'd be curious to see what bech32 "mleku" is as a colour
a colour is about a 4 days mine, for a decent computer... it's still reasonable limitation on impersonators if they don't get the right colour
black is still a valid colour and how many people "pow mined" for more than 3 bytes of zeroes? this takes literally weeks, times more weeks, for each additional byte
