What's also amusing is the corresponding drop in transactions back to normal basal levels again now that all those pools are in agreement about what to do next. This adds circumstantial evidence that someone was injecting all that shit into the transaction biosphere to make it look like there was a transaction volume crisis there that didn't exist.
I pointed out the drop in mempool spam a few weeks ago and nobody commented. What's interesting is fees haven't gone down, probably because the blocks are still full and people have their fees cranked up to avoid stuck transactions. Since the blocks are full, I'm guessing that fake volume with a lot of inputs was clogging the mempool. I also saw last month 1000s of transactions that were invalid, that slowed the network down, indicating an actor with high technical knowledge.
I'm hoping somebody who is more technically knowledgeable than me can figure out who was/is spamming. I know it's not that easy to attribute the transactions. Chances are we could at least get a source IP address, and then work from there...
or more possible because wallet failed to calculate right the fee right now. Today even a transaction with zero fees has confirmed
