Is YouTube throtting some content?

I am looking for some youtube tools to search for lesser posted content. Strange that I clicked a lot of content and I get nothing in my feed. But If I click on other content instantly more of it shows up. No kings. Nothing. I wish youtube would give us more control over our feed content. There's endless possibilities and we have no control it's not right. We could have a lot more filter controls than what they're giving us. We could have number of subs filter to look for lesser posted and more organic stuff. I guess it's really difficult to make a video still.
