Recently, on Facebook, the following images have been trending in my feed, people forwarding them on, claiming that most if not all of them are actually attempts to get women into sex trafficking (click to embiggen):
I'm a bit skeptical, both because some of the posts unironically invoke Pizzagate and because this sounds like the sort of thing that would be in an urban legend, people being sent to a location to find work and getting suspicious, and it turning out that it was a way to lure them into being commoditized. Lastly, the evidence for this being sex trafficking seems to largely be reports of calling the number for details and getting someone with a foreign accent who hangs up when they ask for more details, which sounds more like a general scam than sex trafficking.
