Still very interesting though how they instantly knows that you have something rare in you.
math
they already know that each block has 1 rare sat (first sat per block)
so they know 818k blocks creations is 818k rare sats. and using UTXO spending know the can follow that blockreward forward(based on their bad math of output path) to their perceived current holder address
there are also at block 818k a max total sats of
1955000000000000sats meaning under 1,9550,000 palindromes which they can also UTXO spend check for current address location
im ignoring the bad math of ordinals that breaks the protocol anyways just to give a basic idiots guide to them having a database of 2,773,000 current addresses holding "rare sat"
