Unsolicited approaches on SA
In my experience, anytime a girl approaches me on SA first I'm instantly suspect. I have a relatively straightforward profile. No pics, generic description, usual words about what I'm seeking, and just a couple of buzzwords about some particular body types / dynamics I like.
If a girl approaches me first, out of the blue? 100% chance she is semi pro or pro, or GPS with unrealistic expectations seeing me as a mark.
If I was browsing and viewed her, and she messages me? 75% chance. I used to have a more specific profile, and had a couple of girls write back to specifically comment on it. But now it's less common. (Truthfully, if the girl is decent in any way, I typically at least favorite her on the browse first.).
If I favorite her? 50% chance. Sometimes the girl is someone I would have reached out to anyway and we just have the right connection. But my bs detector isn't 100% when I favorite so I sometimes pick up someone that isn't right. (And sometimes I intentionally favorite a girl I know is trouble because, frankly, she looks hot enough to be maybe worth the trouble, or a challenge to break her down.).
Bottom line: if you have a nondescript profile like mine and a girl approaches you, she's probably "working it". May be self evident to many of you but worth repeating.
