<human>: Provide a brief overview of the text.

I have a 13 year old brother that lives a few states away with my mother and her boyfriend. I was a huge part of his life until I moved away 3 years ago. I visit him on his birthday every year and besides that, I don't have much communication with him. My mom and I's relationship is iffy and the less communication the better to keep me sane. 

That being said, today I found my brother's steam account. He posted a screenshot of him playing Skyrim on facebook and I clicked through. There I found out that he is in the [poni] clan and every single group he is in is also poni. He refers to himself as a 'brony'. He also has 600 hours in TF2 and 260 in Skyrim. He has 60 hours played in the past 2 weeks. This kid attends middle school and has other after school activities.  My mom didn't appear (when I visited) to 'allow' my brother to spend 24/7 on the computer. He hasn't been on facebook since December and I thought it was because he was grounded. 

My concern is not only with the amount of time he spends playing video games, but his profound obsession with ponies. I'm not completely familiar with the internets obsession with ponies but I do know that where you find pony stuff, you also find pedobear stuff.
<bot>: My 13 year old brother has embraced the [poni] clan and calls himself a brony on Steam (TF2 & Skyrim). Should I be worried?
