Want me to check what? We have nothing to do with that account. Anybody has the right to down vote if they feel that is how they want to exercise their voting power. I will never tell someone or try to intervene with what someone or somebody should do with their voting - even if it is down voting. Hive requires checks and balances, and down votes are just one (useful) tool. Besides, I'm not sure why you are concerned, if the account was serious about down voting everything we vote for with any significance, then it would need to power up a large chunk of Hive which I would still deem a net positive!
