As I recently discussed, inscriptions cannot be practically filtered/censored at the mempool layer. It's fundamentally impossible from preventing clever bitcoin users from paying fees to utilize witness space to host arbitrary data.
Clever 'coiners cooperate instead of clashing.
Forget fruitless debates about whether inscriptions ought to be used or not. I want to start concrete technical action to reduce the burden of inscriptions on the bitcoin mempool and fee market by going directly to the source. We should be spending our effort streamlining the actual apps and protocols which are pushing all this data into the mempool in the first place. Who wants to help?
