Seems about right.
I bit the bullet and got Hinge, nobody replies. I even got sent a rose (basically a super like, right? And you only get 1 per week!) and there's no response. The worst is when they're like "aha I'm no good at replying here, add my insta". Checks their insta and they've got 10k followers and certainly won't reply there either.
That's the reddest of red flags on a tinder bio.
