Funny story... when I got laid off I guess one of the other admins shutdown my little cluster. Fast forward a little bit and being a little out of touch it appears I can't remember my password to WCG. I don't want to change it though. <Queue funny part> I guess the admin didn't turn off all my machines I had running BOINC. I guess I still got one machine at my old job cranking them out... Changing my password would break that...
I have a few coins that I keep in my collection to be discovered by others, but with a proxy that travels the world. Sometimes the number gets out there due to me sharing at events, so when I get random discoveries on the coin, I'm not sure if it's the original people saw, or a the proxy.
There is a local cacher (who's name rhymes with PaytownPert) that had a pathtag-like coin minted but with a TB tracking number on the back (100+ tags with the same trackable number). He hands them out with instructions to just discover the trackable number, buy you can see where confusion could arise if people started trying to "retrieve" them or started placing them in caches.
I had a frog one once. They put out 5 of them. Not knowing, when I read the description it said to see if you could place it in a new cache before it hopped away. Sure enough, someone 'grabbed' it from me and put it in a cache overseas. So you just drop it and someone retrieves it and thinks someone else hasn't dropped it and .... you get the idea. Times five.
If your 2nd copy comes back into circulation it would be like that. But less.
