I’m sure you’re right about the techie stuff here.
However, the providers I’ve talked to about it (tiny sample I admit) seem to to be more concerned about someone randomly scrolling through providers and saying “holy cow! That’s my coworker / neighbor / kid’s friend’s mom / aunt”, whatever. That person probably isn’t de-anonymizing every provider they scroll past. But a face is a face and could be recognized easily.
If they pick up a stalker, sure; they can probably be de-anonymized. The ones I’ve talked to about it have been here in town all their lives, or at least a lot of years, and don’t want to be RECOGNIZED.
A few gals have told me about guys who “found” them in their real lives, and they had to get restraining orders. This has even happened to parlor gals I know. Some guy suddenly texts them on their real phone or shows up at their house or says something inappropriate about their kids. Super creepy. Most of the providers who’ve told me about such experiences said they don’t know how he found their real lives. But it was always a regular. Not some stranger who just saw them on an ad mall.
They mostly don’t post their face to stop the casual lurker from recognizing them and knowing their secret. Again, the casual shopper isn’t de-anonymizing every provider, even if they could.
I’ve actually seen a couple providers admit this is why they require PII. They know, in most cases, they are SAFE based on monger reputation, references, etc. but they don’t want to open the door and see their kid’s little league coach or a neighbor or whatever. That’s why they demand real ID. Some of them. The fact that they now know that guy’s secret while theirs is still safe, and how unequal that all is seems to be lost on them.
I do agree with you that seeing a face is more engaging. It makes me more likely to spend more time on the ad, look into it more seriously, it just gets my attention better. I used to never hit like on the photo only board unless she showed face, but lately I’ve been relaxing that rule a lot. I like when they show face, it makes me more likely to book; but it’s not a deal breaker and I do understand why those who don’t are shy about it.
