It's been an issue since at least June, and hasn't been fixed. I post around the forums daily with a 4.23 post/day ratio, and yet is my earning rate. So after about 300-400 posts in the last 3 months or so, I've earned one single credit. I've first noticed this issue after my demotion, so I don't know if there is a link between my usergroup and credits or not, but I do post regularly in Black Ops 2, PS4, and PS3 sections, as seen from my post history and reports. I know it's just fake currency, but it'd be nice I can be allowed to earn credits same as anyone else.
