the super_testnet users thing is about making a transaction with no satoshi input and no satoshi output. thus the inscriptions are not linked to any satoshi's at all. putting the inscription count off compared to how many are inscribed to satoshis

but as shown in many examples in this topic. there are many inscriptions that dont link to intended satoshis anyway
its more of a show that caseys projects are broke and dont fit his own rules.

casey could fix it as its more of a explorer count error by counting inscriptions to non sats. (ignoring non sat tx, but he would be fixing a scam thats broke by other things. so if its broke beyond repair from the beginning via many problems of math/logic/economics, any fix is just trying to make a turd shiny

..
another thing to think about is that we are now seeing transactions not even transacting satoshis. and just dumb memes/json/data/text in dead weight area of witnesses

so now super_testnet's transactions would become spam by injecting alot of transactions with no sat transfer at all
