What I meant was "into dating" rather than merely "has an account".We can safely assume that the general model holds: that of a glut of lonely men seeking out women, while any viable woman's account needs to fend off dozens, hundreds of come-ons every week. Any man who got a DM from an attractive woman's account would be perhaps leery of scams, but LI has strong verification signals that could weed out the obvious catfishing and fakes. Bonus: there would be little risk of underage encounters among professional workers...
Like I said, plenty of LinkedIn men would be into using it as a dating platform, but they will have difficulty finding women who are into dating at all, much less using LI to do it.
