At least the titles are obvious. I've seen other spam(?) that repeats part a phrase or sentence from one of the first posts in a thread. It is really weird. I've seen others that make an intro post and then reply someplace with some obviously canned response like, "That is very nice. You must continue and post your further experiences." I think they have links in sigs, but not all do. It is all very odd.
But then again, for all I know, you could all be Eliza.
