I answer most calls but rarely get them. When it's a scam, it's usually the "play a recording and only use a real person if they push 1 at the end of it to talk to a real person" type. I'll either hang up quickly or if I'm feeling bored and trollish I'll hit 1 and pick apart their plot holes (like if they say there's a warrant or my package is being held, why the fuck do they need to ask for my name?). Then they get frustrated that I pushed the button when I clearly know it's a scam and hang up. I think the reason it's rare that I get those calls is because they also put me on a "waste of time, don't call" list or something like that.
