Anti-Skype resolver?

I am having a lot of problems with little kids adding me on skype and when they don't get what they want they get their little resolvers and ddos me. It normally doesn't bother me, but I have important stuff to do lately. So, does anyone know how to stop people from skype resolving me like blocking my ip or something. I tried the 'Don.vbs and undon.vbs' thing, but it turns out not to really work. Can someone PM me a link or something to get them to not be able to. I know I could simple create a new skype, but either way i will have to add people onto it for 'business' purposes.

Then you have to purchase programs for it. or get fake ip.

Try Privitize VPN, that works, free and unlimited too!
