I want to restrict .remove() method on my data - only allowing the author/creator the ability to .remove the node. Is this possible?
I have the standard users tree and a pair of data trees geoFire and one named details. 'Details' has nodes that contain entries like timestamp and user (which matches auth.uid).

The RTDB has only three rule types: . read.
A remove in Firebase means that you're writing no/empty data to a location that currently contains data:
".write": "!data.exists() || newData.exists()"
Quick table to ensure I got all of them:
data. newData.
exists() exists() .write
