Jack has some pretty good reasons for wanting to put himself "out there" as an artist, but his mum is right to be concerned.
After all, social media sites have rules about how old you have to be, and for most sites, it's 13.
There’s an age limit for good reason. These sites are built with the expectation that you are at least 13, and they may not be an appropriate online space for people younger than that to spend time in.
If you’re under 13 and you’re on these sites, you’re not breaking the law, but you are breaking the terms and conditions of the site, which is not a good way to start your life on social media.
