Many years ago, (decades, even...) I was actually banned from a forum for spamming. Not because my messages were unsolicited commercial garbage like the scam casinos we see today, but because those messages were caught as an attempt to climb the post-count-based rank ladder. I was responding to stuff in ways like "Sure!" or "I agree!", just as a way to get my post count up to reach the next rank. I was caught, and I was banned. As I was new to that forum, I appealed, explaining my naivety and inexperience, and was permitted to participate under watchful eyes. I never broke their rules again.
I don't want TNP to have to deal with ranks-for-posts. Considering we have literal spam games that contribute nothing to the community but count towards your post count, a rank-for-post scheme would be easy to abuse. No thank you.
If you think about it, we already have an incentive program in place. Continue to contribute on the forum or the RMB and you can vote on the region's leadership or run for leadership yourself. That's huge, and I think that's enough.
