I’d like to add that in some cases there can be a toxic element to this as well.
For instance, I have heard from several friends of color that the minute they’ve sent a photo everything goes quiet or they’re even blocked whether on phone or on the app. And it may be that they’re asked for a picture more than others are because of something that arises in the back and forth (eg if the provider searches for their phone number or address and sees some identifying marker). One friend showed me a text exchange with a New York provider who switched immediately from a flirty playful tone to saying “I’ve had bad experiences with people like you so I’m going to have to pass”.
If a provider said something like m, “Since you will be coming to my apartment I’d like a picture for security purposes” that would be one thing (even if cloaking a means of filtering out races, ages, body types etc they didn’t want to service). But just asking for a photo without further explanation deserves discussion.
If a barber, a dentist, a waiter, apartment manager etc said I need to see a picture of you before I take an appointment or reservation, I think we’d be more inclined to speak up about why this can be dangerous. Not to mention that even if the motives are “innocent” how it can trigger sensitive reactions.
