Oregon shooter: "goodbye space robots!"

The gunman (or its someone else, but then its a really weird coincidence) wrote "goodbye space robots" on 4chan, in the same post where he/she wanred people not to go to school in the northwest.

I know its the news shortly after the event (and we know how accurate these were when it came to V-tech, CHS or Newtown) so it may be a steaming pile of $^*&#.

Having said that, I'm somewhat surprised by the term he used. I've just checked the urbandictionary and "space robots" doesn't seem a popular term at all. What drew my attention is beacuse thre's been these forums (and the old Danny Ledonne forums) have a history of people using the "space monkeys" term a bit (original credits go to Palahniuk).

Then this year I had a series of posts where I amongst other info, stressed how Eric used the term "robots" to denote the same type of people.

So, maybe its just me being paranoia or seeing "patterns-within-patterns" where there are in fact none to be found, but I'm really starting to wonder. Does anyone recall any person on the forums with ties to 4chan? Also the shooter was said to mention irish republicans, IRA and RIRA a lot.

EDIT: Made a search. I should tell this as a a parody of a 4chan greentext:

>makes a google search for posts on this forum containing "space monkeys", "4chan", "robots", "IRA" and "RIRA"
>finds pretty much just own posts

It's interesting. He posted on the board called /r9k, which means ROBOT9000 Over time, the board evolved into a place where people (often shut-ins) with severe social issues (Autism, social anxiety, depression, hatred,) go to vent. They commonly vent about hating "normies", (normal people) "Chad" ("alpha" males who get a lot of women) and women.  

People who use this board call themselves robots. So that's where the "Robot" part comes from. A lot of people on various 4chan boards talk about anime. He might have got the "space" part from the anime cowboy bebop. Every episode ends with a black screen that reads: "See you later space cowboy." So "goodbye space robots" could have been him combining those two terms.

It's a r9k term, depressive board when i used to lurk before it got shutdown and later brought back, wouldve been the ideal board for Elliot Rodger as to how i remember it if thats of any significance

Thanks for explanation. I knew there'd be a pattern behind it.

afaik it's just a nickname for the users of the board.Tbh,I never lurked /r9k/,since I just stand for /x/(paranormal board),/out/(survivalism and camping),and /b/(the 'Totally Random' board).
Every board is kinda isolated from the others,with its own slangs and vocabulary.
