Why does my girlfriend have so many social media accounts?

I have been dating this girl she is an artist and she has a TON of social media accounts. They almost seem like alter egos, she bounces around on at least 20 different accounts. Some are for her art others are for picture posting. I just feel like this is so man accounts and she will have alias for some of them. I'm just wondering if this is a red flag.
