My initial idea was to hide certain key words in youtube titles, however I was having difficulty being able to select the titles in youtube so instead I decided to focus on hiding the thumbnails instead. The only major problem I came across with hiding youtube thumbnails was that it does not hide every thumbnail on the page. I believe this is because when you scroll down Youtube refreshes to add more videos but so far it is only the first couple lines of videos that are hidden. These videos are also hidden in a way that if you put your mouse over it you can see what the content actually is. I thought it was a fun way to sort of experiment with Youtube and make video content based solely off the title instead of the image, while my original idea was the exact opposite of that.
