Is watching comedy shows on YouTube that include music and mockery of others considered aiding in sin by increasing their viewership and popularity?

It is not permissible to follow programs that contain Sharia violations such as music or mocking others. Following them increases their fame and viewership, and thus the follower shares in their حكم (ruling/judgment). For "whoever increases the multitude of a people is one of them, and whoever is pleased with the deed of a people is a partner to those who did it." So, merely watching incurs sin upon its owner, and the sin increases according to the corrupting effects that result from it.
