I issued a yellow card for one of his "f#$% you, ciro" posts -- asking if he was getting the message by my yellow card warning (the system PMs you with a message from the mod when a post is tagged as a rule violation).
He still didn't stop. So he posted the same stuff again and earned another yellow card, which, based on his total active point count, pushed him past the system limit -- i.e., red card. So he will sit it out for a little.
