From my experience on YouTube, whenever I want the algorithm to stop showing me certain videos with bad contents or words, the algo seems to understand what I hate and starts pushing them more and more in crafty and aggressive manner, probably to get me see them unexpectedly and be hooked. This made me suspect bad algo, sentient AI or entity that intentional wants to corrupt, attack or hurt the human feeling... more like dealing with something that is aware of my presence and just wants me to be hurt.
Well, I latter realized I'm actually dealing with the system of the world or the matrix, and I understand who controls it. In the system, both online or offline, people are constantly bombarded with all sort of evil or temptations to make them fall and be controlled by the entity, or even be killed.
So, be conscious of this and don't let down your guard
