I thought about how to state my opinion on this, and i will try to make it as understandable as possible.
There are two worlds: The social media world (not for me, but for many kids out there), and the real world.
On social media like twitter and instagram they follow their role models, their cheerlebrities and these cheerlebrities sometimes comment back, follow back, say things like "Thank you" and "You are amazing, too".
It´s easier in real life, because they log in and have hundreds of notifications they can answer or not.
Sure, it can get ugly on social media, but you don´t have to deal with a person standing in front of you.
So these kids are happy that their role model commented on a pic or answered a pn or whatever and think, they are "friends".
The cheerlebrity kid will have a hard time to remember whom she/he said they are amazing/talented/whatever.
Now when the kids see "their" cheerlebrity at a competition they think they can go there and talk to them and ask for a pic or something else like they "talk" (comment) to them at social media networks.
But it´s not that easy, because there are a lot of them and the cheerlebrity is what every other kid at this competition is in the end:
A kid, there with her/his team mates to compete. An athlete on a team.
I can´t imagine how stressfull it must be for these cheerlebrities being at a competition and not being able to go to the rest room without taking pics and talk to everyone. And yes, i think it can get dangerous. If it would be my child, i won´t let her walk alone for a minute at competitions (how sad must that be). You can´t controll who goes into that arena, and there are many crazy people out there.
Don´t get me wrong: I don´t like this whole cheerlebrity thing. I think it is not good for the kids (the obsessed fans and the cheerlebs), it´s not good for the sport.
And i´m sure many of these athletes (or at least their parents) could and should have prevented the hype around their person.
But like someone mentioned before: Most kids want a role model. They will find someone to look up to and say "I want to be like Suzie Superstar".
And i guess it is not easy to stay behind closed doors and keep away from all this, if you´re an talented athlete and performer on a big name gym.
