You can build a Whitelist to protect specific users from accidental unfollows or blocks. Cleaner will ignore any action that targets the whitelisted users.
1. To whitelist a single user, go to that user's profile by long-pressing on the avatar, tap Actions and then tap Add to whitelist.
2. To whitelist multiple users, select them in the following/followers list, tap Actions and then tap Add to whitelist.
3. To whitelist a specific user, use the upper-left button List > Search user.
4. To manage the users you added to this protected group you can go to Settings > Other > Whitelist Manager.
