I am also posting on multiple platforms. The main reason is that there are different audiences at each location. So, it is the "artist's" job to go to where the audience is.

This is similar to bands and comedians going on tour.

In the case of comedians, they say almost all the same jokes every night they perform at a new place. Some I have seen say the same jokes at the same venue because it was a different audience.

Similarly, Youtube, Bitchute, Facebook, Google Plus, Minds, and others have different audiences.

The bad thing about doing this is that you have to check multiple places for comments.
