Michael Seller and Adam Buck opposed the Bitcoin Improvement Proposal 110 (BIP 110) as a threat to the principles underlying the Bitcoin Network. BIP 110 is intended to implement protocol-level filters to reject transactions considered “spam”. Seller noted that the proposal had transformed the spam dispute into a consensus change that could invalidate some of the current valid and paid transactions.

Buck warned that BIP 110 supported practices contrary to the spirit of unlicensed currency. He said that the need for decentrization meant that it was impossible to impose a personal perspective on others. Buck argued that moving forward with BIP 110 without consensus would inevitably lead to network fragmentation.

Buck also refuted the community ' s claim that the Bitcoin core development team was manipulated by external funds, stressing that the funders were not involved in funding decision-making, but merely helping Bitcoin to remain strong.
