Client emails me because he's got a pingback from a site he doesn't recognise. Pretty pleased to have it but when he views the page he doesn't see a link to his site. I view the source and find this <p>blah blah blah <a href="http://quadplay.at/SmarterGroup" onclick="pageTracker._trackPageview('/outgoing/quadplay.at/SmarterGroup?referer=http://www.myclient.com/post-slug/1498/');">Virgin Media</a> tech support….</p> HTML: I can see why WordPress would have generated the pingback, it was just doing it's job but what is this site trying to do by pushing the traffic to the link but spoofing it as coming from my client?
