I just wrote a post on exabot: http://help.xanga.com/topic/exabot-should-be-banned . It turned out exabot *was* indexing my page on exalead, despite my having unchecked "Allow search engines to index my site" in settings.

On the verge of possibly solving that, I login to see 15 new footprints, 14 of which are "rdfbot". Can we ban this bot, too?
