Affiliate Marketing Secrets

I run a website which is just about helpful guides on various subjects, I had a section which was for sports, and inside this section I had a few articles about betting help, for example what does something mean in betting… In these articles I had adsense but also affiliate links to a betting site, so now disabled ads on my site but they say account is still active.
Now my question is, I have removed all betting affiliate links, but am I ok to still have the guides, as all they are is helpful how to guides that people look for, did I just get disabled because of the affiliate links… I have removed these and sent them a reply to say it is fixed now.
Any help on if this is ok or not.

For the past few days Youtube has been unusually slow. All other websites load smoothly. It is definitely not a problem with the computer, since Youtube is slow on all my computers, laptops, and phones. Last night it seemed to be playing normally on some videos, but has since returned to being very slow. Is it a router/modem problem? We have been having recent power outages in the area, could youtube affiliate servers be suffering in our area? Unsure, thanks. Ryan P.

I’m the kind of person that knows a good bit about a lot of different topics. Sports, computers, video games, science, health, biology, chemistry, sports medicine, anatomy, guitar, etc
I know a decent amount about these things but I’m not an “expert” in any field. So how do I go about choosing a blog “niche”?
