Who puts the word “shit” in the name of their website anyway? That’s a good way to make sure a lot people don’t talk about your site. Kids aren’t allowed to say that word, people at work won’t say it because it’s inappropriate, the media won’t say it on air, etc. One could argue it’s actually “sh dot it just dot works” but that’s a mouthful.
One thing I noticed about browsing the youtube homepage on PC is if your mouse hovers over a video, it starts playing, and that puts it in your watch history. So you might be accidentally adding a trash video it recommended to your watch history while looking at the other offerings. You can disable the “mouse hover auto play” by clicking your profile pic in the top right > settings > playback and performance > inline playback.
