Back on January 27, 2006, while I was in Abu Dhabi on business, I posted
this LiveJournal entry. Now, every few weeks, that entry will receive a nonsense comment. Today I got one titled FLbDjyFpYQnhhX that only said "uQSJK6 great site man thx
http://peace.com"
Look at the comments on the original message, and you can see that this is the fifth one of these I've received since last June 21.
What's going on here? My best guess is that somebody is using LJ as a low-bandwidth, encrypted communication channel for something, by sending comments with enciphered text embedded in them to non-current messages. But who, and why?
