Wikipedia:Articles for deletion/Reply to the Arecibo message
Per above, self-published references, no evidence this is even a notable hoax. Also, the entire article clearly fails . Leaving the article intact (presenting event as actual alien contact based solely on self-published refs) gives  weight to a  theory. Without prominent |reliable sources to improve it, deletion is the only reasonable option
