a) Good choice.
b) You aren't doing it.
Ignoring it is just that, ignoring it. What you did was post over here that the person did it. Honestly, if they know they are getting a rise out of you, they'll keep doing it. The best thing you can possibly do is to ignore it, and that means ignore it completely. We don't need to have the dirty laundry aired here. First, like AJ said, it doesn't belong here. You created your own site, your site's issues should stay on your site. Second, by sharing it here, you are actually encouraging it from the people who are doing it.
