But to be honest, very few of the freepers I have known for 6 years have.
Most of the radicals / agents provocateurs have a sign on date no earlier than 2004 or have climbed out of the religion forums where I never entered.
I have this habit when I see a post that is off the wall, I check sign-up dates -- agree with you most were within the last year and a lot within the last month. Have had my share of battles on here but these folks were different. Nastiest group I have seen and the most vanities by new people as well.
