I have been using Youtube for some time. What is the problem I should look for?
For a beginning Youtuber, likely nothing at all.
It's a complex range of issues from automatic demonetisation bots to left wing vs right wing politics and censorship of "free speech".
There are a few high profiles cases of issues and some channels being incorrectly shut down, meanwhile hundreds of thousands of other channels have no major issue at all.
Just go make your content and upload.
