Copying without permission is wrong.
Placing links without prior permssion is usually okay, but permission is preferable, and advising "I have placed a link to your _____ at ______" should always be done, with the link removed, or more commonly modified to a portal page, rather than a detail page, if there is an objection.
Placing banner ads that are selected by the page owner, rather than simply a "toll" placed by the host site or the email list server, makes the page a commercial page.
"xxxx.com" is a commercial site, by definition.
Advertising "The gpsstash page http://www.geocaching.com" at the bottom of every message to this list makes list members participants in a commercial activity.
It would be nice to have a commerce-free Geocaching list, and a commerce-free "gpsstash.org" site.
I think registering "geocashing.com" was all too telling a move.
