True, but only because there are now hundreds of random people on the internet going through all of his reviews and cross-referencing them with other outlets. Kotaku even said that it was a tipster that reached out and notified them about the Metroid plagiarism. If Boomstick Gaming doesn't catch Filip and call him out, thus drawing the ire of tons of people online, none of this additional stuff would get discovered either. It would be an extraordinary effort for IGN to cross-check every single review written by their every single staff and all the candidates they're interviewing with every single review written by all major and small publications. I don't see how this is feasible..
