A GM script to cancel pending follow requests on Instagram. Ideally this would be handled through the API, but Facebook hasn't opened it up to non-business accounts. So we're stuck with something like this.
Needed to handle someone breaking into my account and trying to request thousands of follows.
Install the script like normal and point your browser to the Current Follow Requests page on Instagram.
https://www.instagram.com/accounts/access_tool/current_follow_requests
Upon loading, the page will add buttons to cancel one request at a time, or cancel all pending requests in the list.
The script will create an IFrame so that you can see it working. It loads the target account into the frame and then clicks the required elements to unfollow the account.
