Why this debacle? OP tells that some men in this crowd are not here to see pictures of women in different states of undressed, but are perfectly fine (and even preferring) getting a general idea of a woman's look, with her clothes on.
I think it is a valid opinion and/or preference, that he should be allowed to express. You could discuss the wording, but "harmful" is probably the last thing it is. To whom would it be harmful? Why?
Would any woman that has already have a hundred nudes circulating online care? Hardly?
Will an insecure woman contemplating posting topless pics here, just to get more attention care about it, as she calculates the risk of those pictures becoming semi public? Maybe...
I think the message is fairly inclusive, supporting the more modest women, that there are men less focused on naked skin, but more on other aspects.
Again, I have no dog in this "fight", but wow...
Based on your country location, I am going to assume English is not your first language. So I am going to give you the benefit of the doubt and assume that you are struggling with reading comprehension.
If this was a case of him saying "Be careful with posting pictures for safety reasons," no one would care. The problem is that he shamed women for posting their pictures and expressing their sexuality.
And if he was truly worried about safety, he wouldn't have gendered his statement. After all, there are a lot of non-women on this site who post the same kinds of pictures on here. They are also putting themselves at risk.
If he wanted to support modest women, then he didn't need to put down women who aren't. It's extremely misogynistic, and there are too many people like that on this site.
Also, let's not forget that he inserts himself into situations where he knows there will be sexual promiscuity and says things like "Don't be like that because you could be with me instead." That's a classic Nice Guy. No one likes Nice Guys because they aren't actually nice.
