IcemanD received a cookie on May 25 for being very clever. And unlike in some places, when someone says something clever on BuzzFeed and we say, "Have a cookie," we actually mean it! Except we don't, because this is a virtual cookie and what the hell are you going to do with a virtual cookie?
IcemanD received a "Fact Checker" badge on Oct 31 because they verified or disputed a fact and backed up their claim with some kind of written or visual proof. If we didn't have someone to check the facts, none of the facts would get checked - and then where would we be?!
