The opposite of steganography?

Hiding secret messages in pictures or other writing is called steganography. The exact opposite could be observed for over 20 hours from yesterday in the presumably frequently read Wikipedia entry on the Capital asset pricing model as the telephone number for one SU Khan defaced the entry. I am really a bit surprised that it did not get fixed earlier but perhaps others (like myself) were simply too bemused by it to do anything. In any case, fixing the vandalism does not delete the message since the revisions are available on the history page for the entry. My first impression is that defacing a Wikipedia page could be a fairly reliable way to leave a message in such a way that the collection of the message (which amounts to reading Wikipedia) would not necessarily arouse much suspicion and where leaving the message requires little skill and involves very little risk. Another job for the data facility in Utah?
