He used to post on google user groups.
He has said before that he has had two careers. As he told J. Conti of Bank Index:
I have had two careers, one with NASA and one in the film industry. Currently I am a partner in a small production company.
What exactly did he do while at NASA?
...Prior to his film career, Michael worked with NASA developing advanced image processing tools for the Viking Missions to Mars.
Check out, however, his email address from google back in the 90s.
Jet Propulsion Laboratory-Military????
There's an Andrew Hoppin from NASA who likes to write a lot on the internet. He is a contact of Hertzberg over at Jaiku. Do Hoppin and Rivero know each other? Hertzberg was an aeronautical engineer yet ends up also making thousands of posts and leaving plenty of internet crumbs. Does anyone else find any of this at all curious? Did Kos ever leave the CIA?
Strangely enough there was an "Ender" posting at google during the same time period. One can take a look at some of his posts and wonder, is this how the government trolls used to post? Check out Rivero's posting history. Plenty o' conspiracy theories. It's as if people like him and Kos were "created." It's as if they are opposite sides in a script. How much of the internet is government related trolling?
Then Rivero went to the Free Republic. Soon his own website would become hugely popular, like Kos, Rense, and other head scratchers. Has Rivero like a DailyKos simply been a manufactured part of one side in a scripted, controlled debate? Exactly how much are we getting astroturfed?
Sorry I don't have the link for the following, but this was a letter to Rivero I just noticed I still had but never posted. It was one from a holocaust denier. Michael Rivero has been stoking anti-Jewish sentiments on the internet. There was the crap going on at the unofficial forum with Ender and the others. Rivero is a liar, if he says he had nothing to do with that website. He let it house his archived letters. He prominently had the link up at his wrh website. The link is still there today, even if 86Bush has shut the place down. Perhaps Rivero was 86Bush the whole time?
Rivero Enables A Holocaust Denier Through His Silence
Government trolls have been astroturfing a lot of divide and conquer. The reason why we got attacked was because we called them out for it. We also got attacked because we took the Israeli government to task while exposing the Hal Turner type fakery of an "Ender." In short, we made too much sense with this specific thread.
He made nearly 1300 posts according to his profile, but it appears that only about 500 are available for perusing.
