  About how he'd become engrossed in conspiracy sites.

Anti-semitism is rife on conspiracy sites. I just assumed 'the game' thing was started on one such conspiracy site. Paranoia, hatred and naivety can be breeding grounds for these attacks.

I view it less as a street gang game, and more of a game of 'hunt the Illuminati'. Doesn't make it any less despicable. If anything these conspiracy sites (and its posters) carry part of the blame for incitement.
