The typical message is something along the lines of:
Once they get you over there they will invariably start asking you for personal pics and then money. This eventually develops into a blackmail situation etc.
Hey,
I notice you’re a sub and I’d like to get to know you better, meet me on Google hangouts (insert email address here.)
So be wary of this kind of thing, and please report any suspicious PMs you receive along these lines. They’ll swiftly receive a visit from the banning dildo, and there won’t be any lube used.
Stay safe folks!
