Markovian Parallax Denigrate is the name given to an internet mystery involving a series [1] of hundreds of messages [2] posted to Usenet in 1996. [3] The messages appear to be gibberish; just a sequence of random words.
The posts are often mentioned in conjunction with other bizarre and/or unsolved internet mysteries, such as Sad Satan, Cicada 3301, the Publius Enigma, and Unfavorable Semicircle. In 2012, Kevin Morris of The Daily Dot referred to the messages as "the Internet’s oldest and weirdest mystery". [4] It has also been described by Popmech.ru as "one of the first great mysteries of the Internet". [5]
It is reported that all the posts had the subject line "Markovian parallax denigrate". [3] However, this is disputed; the counter claim being that each message had a different subject line. [6] [7]
These seemingly nonsensical messages were posted 5th August 1996 to the alt.religion.christian.boston-church newsgroup. [8] [3] [9]

This was due to one of the messages' email address containing her name. [10]
In 2012, Kevin Morris of The Daily Dot wrote an article looking at some possible solutions. He contacted Lindauer, who denied being the author of, or having any connection to, the messages. [3] The article states the e-mail account belonging to a University of Wisconsin at Stevens Point student coincidentally named Susan Lindauer was spoofed to cover the identity of the poster. [4]
Other proposed explanations for the texts include an early experimental chatbot or text generator, [2] an internet troll or prankster posting forum spam, [3] a programmer experimenting with Markov chains, [4] or a programmer testing spam filters. [6]
In 2020, an article on the subject published by The A.V. Club proposes the event only became a mystery due to later media coverage, having not been widely reported prior to the 2012 Daily Dot article. [11] The same article notes that YouTuber Barely Sociable made a contemporary video about this topic, opining that the messages were most likely simple spam with no hidden meaning. [11]
