Telemarketing Hitting Skype?

It looks like the advance of telemarketers onto the greener pastures of cheap VoIP Skype calls that was predicted last year might be upon us. A blogger writes, "While having a conversation with my friend, he told me that he had another call coming in and asked me to hold for a moment. A couple minutes later he came back on the line and told me that the call was a recorded message that appeared to be a telemarketing pitch–in Spanish!" On the other hand, as one reader comments on that blog, Skype has a feature that lets in calls only from the contacts you have "whitelisted".
