The Dutch Game Awards, organized by his magazine Control, have been accused of apparent conflict of interest. The winners ofpreviousawards have several times turned out to have been also sponsors for a fee of € 775 (sometimes, indirect sponsors), and some of the sponsored games get submitted despite being outside the submissions timeframe. Diercks has denied that game consultant Leonie Manshanden (two of whose customers were nominated for the 2015 awards) was ever part of the jury, despite the fact that she was listed as a juror until this was publicly called out.
