How the hell do I stop some idiot from making an offer on my guy, short of putting that last skill point on and making him the next level???

I am thinking of searching for his account on FB and sending him a msg telling him to sod off and stop making offers of ZERO tokens. I have cancelled the offer over 10 times in the past 24 hours and they are all the same offer = ZERO tokens.

If he offers 3-4 tokens for him, I would sell as I want to replace him, hence the one skill point from the next star thing going on.

So find him on FB???
