Not stopping, after someone has made it apparent, they did not like your behavior, is the definition of harassment. So, you can call it not harassment all you want, but I think you need to google what harassment is.
As a former site mod, I can tell you this is not harassment, but I do know how frail your lobby is, so just land your violation and move on. I am too lazy to point out the many reasons why this does not fit harassment, so do your worst =^.~=
