Sad that this has to happen. I had an idea that might help. Instead of implementing a 50 post rule, we could limit postings from those who have a poor positive to negative karma relationship. Say a newbie has 1/-4 or something that shows their is a disparity between the two in a negative swing. I don't know the exact formula, but the concept is there. It could be accumulative in punishments like having to CAPTCHA, then u get locked from posting for 5 min, then 10, and so on the bigger the negative to positive karma relationship. I understand that over time people get negative karma, but it should be more positive than negative.
