euro.weblogs.com abused?

European Weblogs can ping the euro.weblogs.com (original purpose)
but now I see that it’s abused by ‘DomainHop‘ Domainhop is submitting a lot of pings from it’s own websites to attrack people.
Title of websites like: learn french kiss will forward you to a domainshop page about cooking and food!
I think I will remove the XML-RPC line in my config. As it give me less joy when a service is abused by others. Any solution for this AC?
