If you doing dirt don't let a broad take pictures of you period.
That shyt is to easy to uncover especially if the picture or pictures pop up online or on social media.
Facebook tells me now when someone posts a picture of me and that I'm not tagged in it. It's says something like so and so posted some pictures you might be in and it gives you the option to tag yourself.
This shyt is sloppy all the way around on the man's part.
Operate like the Navy Seals get in covertly and do your business and leave just as covertly. No pictures, minimize going out in public places, and fool with someone who has shyt to lose just like you do. That will make them as invested as you in keeping things discreet.
