How do you report harassing behaviour?

How do I report someone harassing me to the staff.  There is an idiot, who I shall not name here, who posted in one of my threads an unsolicited offer to analysis my games.  I never responded, and he has sent me several very rude notes about the fact that I did not respond.  I have sent notes back, telling him in no uncertain terms I thought he was rude and to stop contacting me.  Now, he has taken to dredging up old threads of mine and posting there about me not getting back to him.  I need help.

You can block someone by going to account > privacy > block user

http://www.chess.com/home/privacy.html (at bottom of page)

This will keep them from being able to post in your threads, send you notes, game challenges, etc.

not sure if that is the whole story or not but if it was me I would just send an email outlining yur concerns to the chess.com staff rather than doing it here.

Online tasers. Or, if you prefer "artificial tasers". Or, "virtual tasers".

 I am not trying to "do" anything here, other than figure out how to contact said staff. 

Thanks to orangehonda on the info on how to block.

I'm here, you can message me if you need too :)

Online teasers ?!  Hmm.... have met a few over the years....

Maybe you should have said yes, and if he turned out to really be an idiot, block him.
