Second: Tough to say, probably nothing if that's the end of the communication. I hear stories pretty regularly of men being misled into taking someone out on the first date, paying for it, and then finding out a second date or anything beyond that was never on the table for one reason or another. It's definitely rude and vulgar, and people should reserve that for special cases.
Overall, I think people are bitter that dating has such a low probability chance in providing the outcome they desire. But you have to know that going in; "you look good in these 3 pictures and I liked your witty quote" is not necessarily going to lead to a lifetime of happiness. You probably have to expect 1000 failures for every success. But you only need one success.
The “sex toy guy” (and yes, I now imagine the most awkward and presumptuous version of that scenario - perhaps with a flourish of presentation) is clearly socially tone-deaf. But if no coercion or violence took place: Should his name and face be broadcast online so he can be branded “The Dildo King” for life?
The “dirty bitch” guy? Rude and vulgar, certainly. But how many women have made disparaging comments about men — their height, their hair, their genitals - sometimes in front of them, sometimes with friends? We should strive for dignity and respect on both sides. If we accept social shaming as a norm, it shouldn’t surprise us when the pendulum swings both ways - and no one wins in that world. Was the woman in this case threatened or harmed beyond a verbal outburst?
Being in my mid-40s, I’ve also witnessed what a false or misguided accusation can do to a man - careers destroyed, relationships severed, even suicides.
What we’re dealing with is a cultural and moral challenge - not a technological one. And cultural problems can only be solved through dialogue, mutual respect, and shared norms - not through factionalism or digital vigilantism.
