PS. According to my best knowledge it's a Belorussian invention - so called partisan brigades of Internet lol.
No, it's not the invention of any particular group...however, the Zionists are the biggest practitioners by far...take Wikipedia, for instance...any unfavorable mention of anything concerning Jews is immediately censored, and there are 'squads, who patrol Wikipedia to enforce this...but they also go farther: there are numerous Israeli 'hi-tech' companies, legitimate businesses, that are actually fronts for web-hacking and cyber-warfare...of course, the Us Government and it's various 'contractors' are masters at this...so why wouldn't Russians also have this capability?...but what you are talking about is a distorted image...the first 'cyber attacks' in the Georgian conflict were launched by the Georgian/US/Zionist side with web attacks against RIA Novosti.
