As an Alberta Cacher with the same reviewer, I know our reviewer is one of the best and is great at protecting both the cachers and Groundspeak! I have over 250 caches published and only had one reviewed with Groundspeak appeal process, and that resulted in a small tweak in the cache listing before publishing.
As for changing the cache page after publishing, there are millions of caches, would you like to volunteer for the job of reviewing them again yearly to see if they match the evolving Groundspeak rules? Not me!
