How to unfollow?

Go to who you follow, click “All [insert #]”, and then click unfollow on the right of their name

Thank you

where can you see that "insert #"? ╥﹏╥ funny thing, this is also how I ended up following a random person

You can just unfollow now, when you go yo homepage scroll down to your following list and click All then beside their username there's unfollow

oohh, I don't see their name does that mean I only followed the thread?

Yeah only if you clicked the follow under the comment yes, to follow someone you have to click their account and follow them on their homepage
