Posting requirements are pointless. And Purple State, remember that you're GM, not Senator.
I've explained before why these are pointless. Trolls and zombies spam and post on direction. We've had a variety of people that posted dozens of times in a very very short period of time, while the reasonable and intelligent posters who take their time and don't post on the order to do so increase their post count much more slowly.
It does nothing to solve the problem and only hurts legit members. No thank you.
I agree with this. Even if you increase the posting requirements, some jackass is going to spam the forum for a few days and get there. Time limits are the only way to prevent this. I also think you should have to declare your party affiliation when registering.
