I don't have the patience to keep it up for a long time but I barely get any scam calls after pushing the button to talk to someone and then just asking about the plot holes in their script. Like the one claiming there's going to be a warrant for me, why does the guy need to ask for my name and other information? Why would revenue Canada (of anyone who isn't a scammer of some sort) ever want any kind of payment in gift cards? I'll use a tone of voice on the verge of laughter, too.

One time, after I asked, the guy just asked me why I even pressed the button to talk to a person and then hung up. Most of the time they just hang up. Sometimes the English option seems to only be there to make it seem more realistic for those who would pick the Chinese option because the call disconnects right after picking English.

Though more recently I've just been hanging up early in the recording when I do get the odd scam call. They might filter that, too, because even the volume of those calls stays low. Which makes sense because even just making the calls probably costs them something, even if it's just pennies.
