There is nothing we can do in a case like this seeing as we can not prove anything and it's impossible to retrieve IP's through us. We would advise anyone being "pinged" to contact his ISP to tell them about the issue, to see what they can do for you. If you think you know who it is that is doing it, you could also file a police report.
Everyone should be careful when it comes to entering suspicious pages and sharing Skype ID's, joining Ventrilo or using other VoIP services since that is the most common ways for others to get your IP.
