This has happened two times this week now, I'll out of nowhere get a skype call from someone who's not on my contacts list, and the call is followed by a contact request seconds later. First time it happened I didn't answer the call but asked him how he got my screen name, he wouldn't say (or I couldn't really understand what he was trying to say) so I just blocked and deleted him. Second time (just now) I answered the call and asked the same questions, he said it was just by chance that he added me, that he was looking for someone else, and he wasn't involved with SEO/IM. Both times they were indian males. As far as I know my skype username isn't posted anywhere, as they added my personal skype account. Is there some kind of Skype adder that I'm not aware of, or is this just coincidence?
