Yes, I think it's a bit too extreme. It applies only for new users although I'm not sure. It was implemented to tackle spammers but I think it isn't implemented in an optimal way since it ends up annoying more genuine users than really fixing the spamming problem. This was brought up earlier too but I don't know if anything was done of it. I've moved this topic to Website forum which is where the jboss.org team hangs around.
