You are confused - traveling cache aren't being published, haven't been for 8 years.
The purpose of this thread is to identify caches to exclude from statistics and souvenirs, usually because the posted coordinates on the cache page aren't close to where/what a cacher logged them.
Most of the caches on that list are from 2003 or earlier.
Thanks. Originally thought that was the case, but a couple on the list have hidden dates of 2010 (GC59EF) and 2011 (GCD33F). Looking closer, they have logs prior to that. Our bad.
