In the question Do larger blocks make it harder for smaller miners to compete? Why? there are some reasons given for why larger blocks hurt smaller pools. Is this still the case with spy mining?
Spy mining is when a mining pool connects a dummy miner to another pool to subscribe to the latest block hash, without waiting for new blocks to propagate.
Another description of spy-mining is here.
Is the only impact of larger blocks is an increased frequency of empty blocks or am I wrong?
