We played on-stream together and one of my friends said that he was camping. The next day he wrote me a message saying that he would report me because I (13) had streamed a game from 16, then he blocked me and I'm afraid that my twitch channel will soon be gone.
Could it be that you are banned if you stream games from 16 & 18 although you are not that old?
No.
They don't know how old you are
2. Because of such a thing block that there's no violation of general terms
According to the terms and conditions, you can only use Twitch for streaming from the age of 13. So if Twitch wants to, they could lock if they want. But mostly nothing happens.
I'm already 13
Then everything is fine.
