Many celebs have this habit of "hiding their boyfriend or girlfriend" maybe because they get passed around a lot. So imagine posting loads of pics and then having to delete them after you break up. And also some influencers strive on the idea of wanting to build their brand by establishing a parasocial relationship with their fans. Hence, staying single if you are a female social media influencer, a socialite, a streamer, etc. that's definitely the way to go these days.
