Better stay away, as the attacker is very vindictive. My friend is being attacked by the same guy since before I've joined SteemIt (over 6 months now) and when I registered, he warned me not to enter a fight with him. He warned me a lot of times... and he's almost giving up on SteemIt because of that one guy. He's been mostly voting on my posts and not much else.

(All I can say is the attacker is a whale - whose username matches a known US Politician.)
