Indeed they are halving related blocks. But this posting of garbage on the blockchain "to be part of history" is - no offense - an overrated commercial crap. If one wants to add a message to the blockchain he doesn't have to make those fat P2TR ordinals anyway and clearly not pay bitcoins for it, while the people wanting to use bitcoin as... bitcoin... are angrily looking at the mempool "sending best wishes" to the ones spamming it.
And my question is: do you have a personal benefit off this?
I'm asking since it's the second topic I read which you've made on theses "special" block's inscriptions and I start to think that you are trying to artificially create some hype around the ordinals from that block.
