That's just a matter of twisting the narrative: they loved the halving block, so why not start their own testnet Ordinal BS from the same hash as the halving block?
What would it matter if nobody paid attention? They're attention seekers. They don't care to test or learn. They just want to throw it on your face, so you can be the next fool.
All true. But their
victims aren't experienced Bitcoin users. If they'd know what they're doing, they wouldn't be doing it.
By the way: when testnet4 ASIC miners will start reorging CPU-mined blocks, it will have the same effect.
Can we call this a 99.9999% attack on CPU-miners?
