[Here's the suggested edit in question][1].

The OP was asking about security on a shared WiFi connecton.  
They had it tagged as [tag:16.04], [tag:firefox], and [tag:security].

An edit came up that only changed the tag [tag:16.04] to [tag:networking].  
No changes were made to the actual post.

Should such an edit be denied?
