Unsolicited requests for any type of scantily clad modeling is always creepy.
Pros use a real agency or post an ad, they don’t stalk contacts of past models on social media and message them for a session. Completely amateur and unprofessional. Also creeper level sketch. No real photographer does this. Ever.
I’d say this is not normal.
I did a lot of nude photography work for websites over the years, and most of the models were found specifically though ads or they would reach out to me through model applications directly on my website.
A photographer approaching girls online through social media to take their clothes off in front of a camera is… 100% sketch.
What an oddly racist remark to make.
