I hate to disagree with a respected member of the forum community. But I must! No doubt providers are overrun by time wasters, but a quick video call from a prospective customer that is offering repeat business doesn't sound like anything more than the quick and direct interaction you are referring to. He's not asking for a 3 fingered selfie, or a full body pic with face, or a dick pic with a can of soda etc...
If I had a dollar for every time I got the "my pictures are up to date" and it turned out not to be the case - I could retire to...rural Pennsylvania! lol
Or I could be both wrong and high maintenance. Jury's still out...
