I don't think they're required to meet that 20 posts a day though.
No, but providing an incentive for 20 posts a day means many of them will post any old spam in an effort to reach 20 posts a day to maximize their earnings.
And for somone who have pretty much the whole day to spend in the forums, 20 quality posts i think is easily attainable.
Sure, there are
some members who could make 20 on-topic, constructive, and high quality posts in a day. But there are many more members who struggle to even make a single constructive or high quality post. Incentivizing them to post 20 times a day simply results in 20 spam posts.
If the Campaign follows the Rule , whats the Issue with the DT members ?
The campaign promotes and pays for low-value, pointless, and off-topic posts, all of which are against the rules.
