don't u guys understand that my dms are opened ONLY FOR GIRLS ?

I see this a lot. Women think men are stupid and don't read. That has nothing to do with it. Men work by numbers. We are used to being rejected in our advances. We are used to hearing no from women we are interested in. If we let rejection stop our pursuit we would never get anywhere with most women. So we become conditioned or are biologically driven to take a shot at it. What's the worst that can happen? If the overture ends in rejection we are no worse off than if we hadn't tried. I doubt you'll find many men who have not learned that persistence can pay off.
So instead of getting vexed about how stupid the male gender is just ignore or block and move on. Your blood pressure will thank you.
