Interesting, indeed. With their current pay rates and limits, you need to write 95 posts per week to get the max. payout as a Legendary member and 125 as a Hero member. That's quite a lot. I personally find it hard to even find just 50 interesting topics per week where I can post a constructive answer / new thread or guide.
I guess at least it's gone down a bit from the 200 posts per week cap in OP..

I wouldn't doubt that you can churn out around 100 posts a week, and keep them substantial enough though. Only a few select users can do that though, and I'd prefer if Stake only hired some of the best users, and got rid of the ones which clearly aren't up to standard. Not just Stake though, I wish more signature campaigns had a higher threshold. You know, something akin to what companies do today with sustainability, they use it as a way of marketing themselves. Now, it kind of does my heading in, but I'll be honest seeing a signature campaign actually trying to look after the forum; I'd have respect for that. Especially, since campaign managers check every post, supposedly. I kind of wish they reported the one's they think aren't up to standard.
Alright, I know sometimes you can get that in between where they won't pay for it, and technically it doesn't break the forum rules as it might be substantial enough. However, I know there's cases where they are breaking forum rules, since I've seen it myself, and I'm not the poor sod that has to clean it up. Hilarious, globals, and those that moderate the main sections are.
