There was one a while ago that a travel 'influencer' called dreaming_outloud posted on her story. I think it had the same caption and filter/editing style of blue/orange tones, although the picture was different. She also had a jacket that dreaming_outloud owned. It started with her just complaining about copycat accounts in general and people not being 'original' or 'themselves'.
Anyway rather than contact the girl and say hey can you change it/this looks similar to one of mine, she posted a screenshot from the girl's Instagram (didn't block out her name) on her story calling her out, and a ton of her followers went to attack her to the point she ended up making a new account. It wasn't even an original caption that she came up with tbh - pretty sure it was a quote someone else had said.
