I would have to say zero so far. I have sent messages to many women, most who do reply want to communicate offsite right away. I do have an email that is usef exclusively for M2 but, found out that most seemed like “fake” accounts from ppl actually overseas somewhere. From their style of writing, they did not seem like typical Americans and the way we communicate. Sorry to say, I’m thinking that most accounts on this website are “fake” accounts.
But, in all fairness, I think I find a couple of users that where actual real ppl.
My guess is M2 keeps the fake female accounts to help increase the ratio of female vs male. Otherwise if they eliminated most/all fake female accounts the ratio for men would be way too high.
