I mostly agree with Haal Haal Pandit. If you have been watching shitty content for a while, YouTube most likely will recommend similar shitty channels on your YouTube feeds.

YouTube does provide an option to not recommend videos from particular channels you would rather not watch. It has been useful option for me.

Plus, you can create multiple YouTube channels from your same Google account to watch content of only particular subject matter on that individual channel so that related or similar videos gets suggested by YouTube only on that particular channel and not on your other channels. Switching between your channels is just two clicks. Super useful feature for me.
