Gamers Harassing Gamers

There's a gamer on twitter @DraconickGaming who's been harassing a friend of mine (and fellow gamer).  Targeting him and the people he works with.

What kind of a loser does that?  Let's end his kind of abuse.  If I wasn't blocked, I'd confront him myself.  Why this guy can't leave people and products he doesn't like alone, I have no idea.  But I'm not going to lay down, do nothing, and let him destroy my friend and his small, independent gaming business.
