Thanks for reaching out. YouTube doesn't subscribe you to channels automatically. Could you confirm if it shows "Subscribed" on the channel page across devices? Also, do you have any third party extensions installed on your browser: https://yt.be/help/Jij7 ? Let us know.
Nah I don't have any extensions related to YouTube downloaded on my browser, and even when I unsubscribed from this channel their content is still showing up on my subscription box feed on both my phone and my tablet. Is their anyway I can stop seeing this channel
