All campaigns that require a certain amount of post each week could be seen as adding more spam to this forum, Yobit campaign is paying people without the need to reach a certain amount of posts how great is that. They also never said that you should post the max amount of post they are willing to pay and when Yobit did announce the relaunch of the signature they directly added some extra rules to this campaign so they did thought about the problems from the last signature campaign.
It's never good to judge about a whole group of people when some individuals are the main problem, in each campaign you will find rotten apples and if people go to far you have always the forum mods and staff that can kick/block people from joining a specific campaign.

Poor quality and unconstructive posts will not be tolerated on this campaign. You don't need to write an essay with each post but one word replies in spammy off topic threads or streams of constant half-assed one liners will immediately get you removed. Please just put some effort in to your posts and you'll be fine.
Users with negative feedback from defaulttrust members are no longer permitted on the campaign. If you sign up you will be removed.
Any user who hasn't made a post in over a month will also be removed.
