Most of these calls are from Indian call centers. UI can't be bothered wasting my time to lead them on, I've tried and I always end up laughing at their pathetic lies, so I found a few grave insults in Hindi to use when I talk to them. They are criminals, so they don't deserve any courtesy. They scam people out of huge amounts of money, and often steal controlling access to their PCs and bank accounts. The phone companies could block all of these calls, but they are making money from them, so they don't care. I don't get as many as you though, just about four so far today. Maybe my aggressive attitude to telling them what scum they are has some positive affect after all.
