"Content" is the common denominator word for everything that ends up on a platform. Some of the content is art, some is DIY guides, some is game playthrougs. And some of it no one will even bother to classify because of how random or useless or bad it is. Some "content creators" make this stuff specifically for the absurdist joke of how pointless or offensive what they are making can be while it is not removed from the platform and still gets them views. For this stuff, there is lack for a better (or more specific) word than "content".
