Stars to which messages were sent include: The 1986 Poetica Vaginal signal, briefly transmitted from the MIT Millstone Radar, was an techno-art project created by Joe Davis who was concerned about government censorship of messages such as the removal of genitalia on the Voyager probe record.
His response was to use a sensitive instrument to record the contractions of a woman's vaginal canal, convert it into analog signal and digitally map the input into a phoenetic audible representation (or voice).
The main defect of the "Hello From Earth" is an insufficient scientific and technical justification, since no famous SETI scientist made statements with validation of HFE's design.
As it follows from [1]: "After the final message was collected on Monday 24 August 2009, messages were exported as a text file and sent to NASA's Jet Propulsion Laboratory in California, where they were encoded into binary, packaged and tested before transmission", but nobody explained why he hopes that such encoded and packaged text will be understood and conceived by possible extraterrestrials.
On 13 February 2015, scientists (including Geoffrey Marcy, Seth Shostak, Frank Drake, David Grinspoon and David Brin) at a convention of the American Association for the Advancement of Science, discussed Active SETI and whether transmitting a message to possible intelligent extraterrestrials in the Cosmos was a good idea;[3][4] one result was a statement, (which was not signed by Seth Shostak or Frank Drake), that a "worldwide scientific, political and humanitarian discussion must occur before any message is sent".
