Yeah, okay. Whatever...
I tried to contact the so-called acct. holder with no response. There was no clarification of intent, nor were those names ever scrawled into the logs of the cache in question. I understand that it's possible that someone was just splitting & backlogging, and realize that there's some potentially less-devious intentions at play. Fine. Cool.
My initial reaction to what appeared to be a false log was to ask the "cacher" what they were up to and to delete the logs. I didn't hear back, either way. Admittedly, I got a little worked up about it at first, but really, it's pointless. I'm not too concerned about it.
Anyway, thanks for the feedback. I appreciate the different points of view.
