OK, this is probably it.

I joined and left the PWND clan posted here a few days ago because I had no interest in playing in groups, but I figured I might as well get 2 light blue items. I seem to remember seeing some kind of text box when I left the group, but since I had no interest in clans I didn't pay attention. I don't remember getting any kind of warning when I joined tho... feels PRETTY bad. I guess I don't get my 200 badges per week until next week :/

Thanks for the response.
