Use an exif metadata stripping tool like "scrambled exif" to clean your images before posting them.

Or use GrapheneOS which has a hardened camera app that doesn't save exif data in the first place. 

 Dammit I've been scrambling on GrapheneOS 

 Nice. Will check both these out. :) 

 Would be nice, if this option could be integrated into the #nostr app @miljan
