Keep spamming the same unofficial Jagex "source" doesn't mean a thing, especially when it contracts your original post that the Jagex OSRS team's claim of 550k OSRS members.
137k + 255k = 392k subscribers only according to your latest post, way way way way way x 9000 below the 550k from the Jagex OSRS team and the 765k from the official Fukong 2017 Financial report.
Meanwhile, the actual official Jagex Seasonal Overall Hiscores show:
34,292 OSRS players
280,159 RS3 players
