Why does Tinder work for women but not for men?

Got a friend (female) who's bi on Tinder. She gets connected with other bi women all the time and plenty of straight/bi-curious women too. She blocks all men. She said plenty of the women want share phone numbers so they chat to know each other are genuine. She's met a few of them for sex, etc, and talks to a bunch regularly outside the site.

I'm on Tinder and I never get any connections at all, except two that were scammers. Both different scam approaches, but I knew straight away and just 'played' them to drag out the scamming. Sadly no genuine connections. So I can't really work out why it works for her but for me it's a total disaster. I have genuine pics and a genuine intro (same as for every dating site I try out).

FFS!
