I had a coin stolen by someone who calls himself blairdonny. Stole & destroyed a cache in the South of England which had,amongst other things, a coin of mine in it. He left the GROPE message on the cache & coin pages. I left a short reply on both & am now getting abusive emails from him threatening to come up to NE Scotland and destroy all MY caches! What a sad, petty individual. Reported to geocaching.com of course but what can you do?!
