If you're dealing with a possible scammer, that scammer might ask you to send them something as part of a scam.
A picture, a Word document, or anything you can attach to a cloud storage link will do. Once you do, you'll need to prepare a digital file to send them. Working that into conversation shouldn't be too tricky, the nature of the internet makes asking for location a routine part of an online discussion-does anyone else remember A/S/L? If you don't already know the location someone claims to be from and are just trying to figure out whether they're genuine, you'll need to convince the person to say where they are before sending them the link. In the case of our fake job recruiter, the scammer claimed to be in the US, but they accessed our link from an IP address based in Nigeria.
But, even if they are, there's a good chance the VPN will show a different location from where they claim to be. Anyone can use a VPN to mask their real location.
