My edumacated guess is these posts are done by a 'bot, which automatically signs up a user on the board and makes the post. The s/w used for this board is popular and a known quantity, which makes it easy. That's why more and more sign up scripts generate a gif image with a word that you have to type in to complete the process. Ironically, some of the most significant OCR hueristics being developed today are being done by those trying to defeat these measures.
