Ranks were updated quite a while ago now, resulting in clraik rank needing 25+ rep (you start with 10). This is because there is a lot available at that rank, and we determined it was safer for everyone involved if it was gatekept from potential spies and other nasties who could just spam their way to 50 posts. It's unfortunate that you've only seen it now, but this is what is explains your situation. Looking at your posting history for the past couple of years, my guess is you're back for AC.
