@TeamYouTube Dear YouTube Team!
I was building my channel for years. I got approximately $80 a month. I know it is not much, but in Hungary my monthly salary is less than $300. Then my channel got suspended without any warning and now I barely have enough money to buy food.
When a channel or account is terminated, you'll receive an email with more details about the reason. If you think it happened in error, you can always appeal. Also, here's more info about account terminations, including why it can happen: https://yt.be/help/WX8p
