Ever since teens had access to social media, there have been studies on the matter, (i'll admit, that in early years they were pretty scandalous, but now they try to act as more of a guide or recommendation for parents).
The Fediverse is mostly handled by moderators and the community (like Reddit used to be), so when there's an issue regarding ill behaviour, it is usually handled inside that community. (And besides, instances have their own rules too.)
It's toxic waste, get the hell out of there. ๐โข๏ธ
Because i was born in the year 2000 so my perception of teenagers and social media is still recent, also i have a younger sibling, and she has shown me the kind of crap teens are on today.
Edit: Ok, i may have been a bit too vague with this comment. So i'll be more specific. โฌ๏ธ
Some platforms like Tiktok, Instagram, Snapchat and YouTube have been nothing but harmful to youngsters (from all ages), due to their manipulative algorithm and poor content management.
So i do believe there should be a much more stronger restriction in access to those platforms.
Something like, you can register at 16 with your parent's permission, or something like that.
Now i now that sounds very drastic, but consider this:
1- It has been proven time and time again how social media has done more harm than good to teenagers.
2- I'm only talking about about platforms owned by the big corporations, platforms here on the Fediverse are (from my perspective) much more safer (in the sense that you don't really see harmful content if you don't want to).
Here you got one source (again, of many):
