Dating expectations in Miami vs elsewhere

So I (28f) feel like this is a weird topic but I've been single for almost two years. I lived/grew up in New England before moving here - almost two years ago. I've been using dating apps consistently but have found this weird expectation: deleting your exes from social media.

Before moving, I'd never once encountered this issue. I've dated people who had photos with their exes from years prior and never thought twice about it and vice versa. From my experience, it's unheard of and in some cases, deemed "shady" to delete photos - unless the relationship was exceptionally toxic.

Well, I've been going on dates recently and noticed that specifically here, in south florida, it's almost like a universal expectation to scrub all traces of them from social media after a split.

My ex and I dated for 3 years - we aren't friends & it was my choice, but we ended on amicable terms. I have over 200 posts on my instagram, exactly 5 of them being with/of my ex (the most recent being from almost two years ago right before we broke up). I've had several men who I matched with - most of whom I never had even met comment (and heavily accuse) me of still being hung up on him due to the fact I never went back and deleted those photos after they scrolled to the bottom of my instagram. It's frustrating and a little hurtful but I wanted to see other local's takes on it. Like I said, I'm not sure if it's a "New England thing", or if I've just had bad luck encountering insecure men here.
