Are Mining pools spamming the network with fake transactions to prop up transaction fees and push a false narrative about full blocks to support BU and usurp the power to adjust block size?
Don't know about other mining pools or mining farms, but viabtc is actually prioritizing transactions that are included in their database through their tx accelerator service in an attempt to support BU. Don't know we can consider this as spamming network with tx they like while neglecting other tx but they are doing it from several weeks.
