Who or what is George Rajna? I don't know maybe this question seems off topic but anybody get the chance to look at vixra.org archive? 

It seems it is blown up by some manuscripts from a guy, which is called "George Rajna", and more interestingly all of them are about some ridiculously (excuse me I didn't find another appropriate word!) hot topics in quantum physics or general relativity. Sometimes in my spare time I just look for crazy things for fun in internet that seems really funny to me. I can't believe "George Rajna" is a real guy (I mean someone really exists with his name or identity!) but it seems it's a just article posting robot, which blow up vixra.org?! 

Again, I know maybe it sounds completely off topic but I appreciate if someone has any idea about people post their article (If you could call it a real article, which I'm not sure really?!!!) in vixra.org?  People do it just for fun or really they have some serious intention?!
I don't think this is a bot. It looks more like a (somewhat misguided) real human, who may or may not be operating under a pseudonym. Based on what I think is their LinkedIn profile they seem to be a reasonably well-educated person with extensive experience working for IBM (or so they claim), so not your average crank. That said, their contributions to vixra seem fairly cranky to me, especially since said contributions mostly consist of extensive compilations of existing material, without a lot in terms of attribution. 

Note that there is also a website apparently written by a "Rich Norman" praising George as "a mouthpiece of the possible". Rich Norman claims to be an "artist" of some sort, who has also written some books published by "Standing Dead Publications" (owned by Rich Norman). The over-the-top praise, strangely flowery language, and the unstructured list of what appears to be pretty much the entirety of Georges work makes me think that there is a connection of some sort between George and Rich. Maybe they are the same person, but it may also be a case of a fringe artist being intellectually attracted to a fringe scientist.
