Like Wimseguy I've cringed a lot lately reading those logs. Why spoil it for future finders? I guess some people feel like they're helping them out but I bet no one wants help! Sorta defeats the purpose of "finding".
I had a similar log left on one of mine a while back but just shook my head & left it.
I'd ask for an edit but wouldn't it be nice if we could edit logs on our own caches?
