As someone who’s been reading this for months, @Tom_from_NYC, your concerns about the safety and privacy of unfollower tracking tools are very valid. Based on all the posts here, the best method these tools use is comparing historical follower lists, which means they can’t access real-time unfollow events unless they have permission to your account data—anything else would just be an estimate from public information. There is always a safety risk when granting third-party apps access to your account, including potential privacy breaches and even violating platform terms of service, which could lead to your account being suspended. The safest (and arguably most ethical) route is simply to avoid these tools or only use official analytics features from the platform itself.
