Bro, don't stop. Keep flagging him. You'er a soldier :) I saw that you stepped up, and that's one of the reasons why I also stepped up.

Yo, that's so awesome that it was because of me!

Unfortunately, downvoting doesn't drain upvoting, because they are in a separate pools now since the Hard Fork. However, the good thing is that his rewards can be taken to zero and even he cannot downvote everyone to the ground with his limited downvoting power. And with the community having our backs in case of retaliation – he cannot fight all :)
