Since there is a lot of people having the same issue, I might look into the API itself to speed up this unfollow process.

It's now unfollowing correctly after a few refreshes and script restarts, the api limit keep getting hit but after 5 mins it'll unfollow a couple more so it's ok!

Thanks for making this.

keep getting
