Exactly this. That isn’t a real friendship: it’s two people who are using each other to bump up their followers and engagement on their Instagram posts. That person isn’t always just there: she’s there at the moment because it is mutually beneficial. Sian has a Disney following and her friend sells Disney themed clothing. They are using each other; it’s more of a business arrangement than an actual friendship.It proves the point though. She is gushing over this person she literally met for the first time 3 weeks ago.
