GrindHard is very aggressive I agree. He still manages to sneak me a Skype once a month telling me how I've let him down for not going on his network. Too much aggressiveness is easily mistaken for desperation, and that makes me uncomfortable.
All in all, he's a nice guy though, don't feel he should be banned, he's actually been quiet as of late. Grind, I know you're watching out there... tone down the sales pitch, your network rep will speak for itself if it's solid, no need to shove people through the front door.
