For the more general question- I think it's inevitable in any sport. It happens all the time and it's just a part of the game.
One a personal note regarding what I believe to be a positive aspect of some of the cheerlebrities, is being a positive role model. My daughter loves Maddie and became a huge Maddie fan after watching her on video, but especially in person at SE practices. She didn't know Maddie was "famous" (for lack of a better word), but she knew that there were qualities she saw in Maddie that she loved and/or admired.
In most cases that would be the end of the story. However, Maddie took the time to get to know my daughter beyond just sneaking a wave to her during practice. Maddie was (is) always so sweet to her and it has been very encouraging. My daughter is a flyer and got hurt last year. Maddie (along with
mstealtoyou daughter) helped her overcome her fear. She gave her one of her old bows and CEA tank top (it had been Maddie's when she was my daughter's age), she bought her little presents throughout the season for encouragement (like when she hit a new skill or was discouraged with her performance at a competition). These little things meant (and mean) the world to her and made such a difference during some tougher times. Maddie would often take the time to go watch my daughter's performance (barring her getting mobbed beforehand lol) and tell her how proud of her she was. That is kindness, compassion, dedication to the sport. My daughter is just one person. Granted, we became friends of the Gardner's (I absolutely love Sarah!), but still-my daughter is just one person. She's not the only person to look up to Maddie, nor is she the only person Maddie has treated w/such kindness.
I could go on and on, but I'm sure plenty of you would get sick of hearing about it -so I'll leave it at that;What do I think of cheerlebrities? I think just like any sport, they can have a positive or negative influence over adolescents and children. I'm fortunate that I had the privilege to experience one who has such a positive influence on kids. Instead of posting about boys and where she was eating every 5 min., she was posting about someone who had written, emailed, messaged her, etc. I am also fortunate that there are so many girls at CEA to whom I can attributes many of these same qualities (like
mstealtoyou daughters and quite a few others). We often talk about how we don't like the aspect of such young girls being on the same team as 16-18 yr olds, but I truly do not worry about that as much at our gym. It may seem that way on the surface to some people I'm sure, but really many of those girls are so precocious and are always studying, cheering, or competing. So the aspect of cheerlebrities doesn't bother me. Even if we're talking about another gym- let's say Kiara Nowlin from Cali. If my daughter looked up to her bc of her athleticism and talent w/tumbling, and had a poster of her on her wall as opposed to Miley Cyrus, I'm pretty sure it wouldn't bother me (in fact, I'd probably prefer it).
