I am not sure what kind of side effects this may cause beyond the fact that it works, but I got a little more specific with the filter and confirmed that it works in UBlock since UBlock can use AdBlock filters as well.

These directly look for the internal text for any of these elements, so any element with "People also" in the text portion will be removed. I figured doing it this way is better because they won't randomly generate the internal text like they will the classes and stuff. It works for me just fine in Chrome.
You can change it to be the exact text if you want or have issues.
In UBlock you need to go to the icon that says "Open The Dashboard" in the tool tip. It is just an icon on the right side of the popup when you click the icon in the browser, looks like a settings icon. Then select the tab that says "My filters" and paste the provided code inside.
In AdBlock Plus, click the ABP icon on the right of the browser and click the setting icon on the top right. Then go to advanced on the left menu and go to the bottom and click the button that says "Start Creating my Filter List." You can paste the provided code in there as well. I haven't tested it on Ad Block Plus as much as UBlock because I didn't see a reason to do both, so proceed with caution.
Also, you could probably add additional ones for other items you want to remove from the browser.
