I maintain very tight privacy options on Facebook, and I want my Facebook experience to be friend-centric. Is there someway I can automatically untag myself from every photo someone (say a family member) uploads with myself tagged?
Sadly, it doesn't look like you can automatically untag photos of yourself from specific users.
> There is no way to prevent someone from tagging a photo with either your username, or your name as a tag. What’s possible is you can prevent other users from searching for photos of you.
The only thing you can really do is to make all tagged photos of you hidden to others:
If you want to remove several tags at once, you can go into the activity log page, check the boxes of the photos you want untagged, and a button will appear in the upper right that says "report/remove tags." Click that button and select the radio button for untagging.
