Here is a copy of an email I just got:

Just to let you know your cacheopedia is wide open for hacking.
I was looking at the sight listings and there is an edit button there. Out of curiousity I clicked it and it allows me to edit the listing.
If you go there and look at the navicaching.com link notice there are now three questionmarks at the bottom of the listing.
Thought you may want to know.
