My friend has recently had a situation were thousands of spam/fake followers (currently at 8000, and climbing every minute) are bombarding and following there account. They have changed there password but the issue is still occurring. Just wondering if anyone can help or knows a way to stop it. Many thanks
I'm afraid that this can't be prevented unless you choose to make your account private (in which case you still may receive follow requests). The fake accounts can be manually blocked though.
You can go into settings > apps > find the app that might be causing this and revoke permission. In my experience, it's probably an app that's causing that. Revoking permissions should fix it.
