What you're saying is fantastic, and unfortunately, in my opinion, idealistic.
Of course, I'm all for trying to educate people about how to act online, how to treat people better and how not to be abusive towards women.
But let me put this into perspective. Men act exactly the same way on dating apps in every single country in the world where they're available. In Vietnam, in Nigeria, in Chile, in France. (having travelled a lot, I've even seen it with my own eyes)
No matter which culture you're in, the same patterns emerge. Women are bombarded with messages, including desperate and abusive ones. While men are left struggling to get any responses.
This is simply how human nature interacts with dating apps. It's not socialisation. If it were socialisation, you would see men acting differently on dating apps across different cultures.
Remember: the genes hold culture on a leash. Not everything is about socialisation.
There are some possible methods that could improve the problem: Make unsolicited dick pics illegal. Make it a requirement to verify your identity on online dating apps. Improve the reporting systems on dating apps.
And sure, educate men about how to act on dating apps, but this is by far the least effective of the solutions.
