I've just gone and had a Google about Bumble and Tinder droughts....
OK, so if lots of people swipe left on you you start getting edged to the back of a virtual pile.....That's a bit tricky if, like me, you have a deliberately Marmitey bio, to put off people you really don't have anything in common with. It's almost as if you should cultivate quite a bland and broadly attractive profile, just so that lots of people swipe right on you.
But, to be fair, I only have 2 photos on my profile, and none of them full length, so I guess the first thing to do is to get some more photos done. Then maybe close the profile down and re open.
I also learnt that, when you first join, you get edged to the front of the pile for a while, no matter what your "ranking", so you do get seen more at first.
God, the jumping through of hoops, bloody hell!
