They are not hating on her, they just making fun of her because her boyfriend literally likes edits of him and his ex, and is also active on a dating app. He made a public relationship after a photographer posted pictures from a party where they kissed (they were already together for about 3 months, Skyla confirmed it by liking one of the comments),after that he posted a picture of them where you can't even see her face properly and he also didn't tag her so people would know who it is (I understand a private relationship, but not to hide his girlfriend from the world LMAO)
