I get loads of these scammers contact me.
A couple of friends and I deliberately play along and waste their time. It can be quite entertaining. Especially when you deliberately veer away from their planned script.
The nature of the messages makes me think they are set up like a call centre. (Scripts, handing cases over to different operatives, etc.)
Some of them are so obvious, I wonder if they use it as a filter to weed out anyone who isn't very gullible.
Some of them are actually quite convincing, and I could see how someone might be conned, if they'd not been exposed to the others first.
I'm wondering how far away overlaying the picture from the fake profile on a video call is, I would have thought a powerful PC would have enough power to do it.
