Another important reason the system shows you things you don't like.

There are times the system or the matrix tries to achieve a goal or to make an event successful. Incentive or reward in form of higher views is created on YouTube for example, for people to promote certain words or tags (or both). They become trending tags/words, and are forced on other people because the system desperately wants the event to be successful. So, no matter how much you dislike videos with the words they keep coming. The events or targets are things you may not believe if you are told. They are mostly evil agenda or deep things of life hidden from majority of people.

This also happens offline/physically... You could also notice them on mainstream media. You may have heard the news people on different channels repeating thesame words during a time period. Or seen different gamers unexpectedly gathering at thesame place to find a hidden treasure or something like that.
This is the matrix at work, trying to achieve a goal. Those who are used may not be aware there are many other people like them that are used at thesame time.
