Are any things that immediately make you go nope or turn you off when you're looking at profiles on dating apps?
For me, it's anyone who's obsessed with Harry Potter, i.e. overly mention HP in their profile or go into detail about their sorting house/have a ton of pictures with HP merch. Like, I like Harry Potter as much as the next person, but it's an immediate turn off when someone's entire personality is based around HP.
I think it's also because a ton of 'queer' women (read straight with ridiculously short bangs/coloured hair) seem to be obsessed with it, which makes me less likely to try and match with them.
