What's with the lewd profile pictures?

Often enough I've been coming across very lewd profile pictures when I'm reading stories on this site. When I do read a good respectful story and I see that kind of photo- I'm thrown off. I try to ignore it at times and even try to change my own mind by checking their profile. Very rarely it's some people genuinely being a good person that just have confidence in their own bodies.

But then I find it's often the case where it's mostly female pictures in some bikini, barely covering their privates, or outright clickbaits for the perverts on this site. I came to the conclusion that many of these are fake profiles and have 'men' running them. Why? I have no idea. So I want to know what everyone else thinks people who use lewd profile photos on this site.
