Snap is largely a waste of time, although it's a good platform to spam randoms and harass girls.
Not lying about yourself will backfire more. You can buy 10k followers on Insta easily, and it will catch the attention of any girl you talk to. That's how shallow they are.
I've had a few conversations with girls on Insta, and a couple who even don't mind talking to me. And with a completely anon profile, and opening with dick pics. If you're creative/funny/confident, you can get responses. It's a numbers game. I realise these are cliches, but there's some truth to them. Your best chances are frauding an Insta profile, adding and messaging hundreds of girls (find their IGs on Tinder or just browsing Insta), responding to their stories etc.
Girls on dating sites are either just there for validation or you're competing with thousands of guys, you have no chance. Girls on Insta and social media don't get as much viable attention as you think. There are thousands of girls. It's really your only chance with girls in the west. I had this Canadian Stacey genuinely wanting to talk to me because she thought I was funny, I sent her dick pics and trolled her stories. She said I was the funniest guy in her DMs, and this was with a burner profile.
