I get about one scam call a week on average here in Windsor, Ontario, Canada. Once 3 in a day. Once nothing for months. Plus I get at least two or three times as many "almost calls". One started my day today - I picked up, "Hello?", no one answered, "Hello?", no one answered, "Hello?", no one answered, "Hello?", no one answered, some mic sounds and clicking and hangup. I don't know how or why.

My solution: I engage them and add "key" phrases and concepts. If I feel like it I'll draw it out as long as possible to waste their time, or I may jump to the point. I introduce politics in a chitchat way to pull them in as much as possible, while pretending to accommodate them. At first I sprinkle the conversation building up to dominating the conversation with bomb-making, terrorist banter, drug smuggling, and pedo terms. Often enough they have hung up or resort to calling me a motherfucker. I tell them the whole thing is recorded and tracked by the NSA and they'll be hearing from them soon.
That's assuming I have the patience and humour. Otherwise I tell them that I understand that times are what they are, but scamming isn't the answer, even if you consider it international cyber war. Punch up.
