Yeah this is one of the more malicious things out there, those numbers are a fucking trap. I called one for a friend when I was a teenager and noped the fuck out after they kept trying to trick me into telling me where they lived. It left me extremely disillusioned. At one point the woman on the phone asked me "okay so what do you want me to do?" when I refused to give them an address. I don't fucking know! I'm a confused teenager who is worried about my friend! You're the one who should fucking tell me!
