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.
When some accounts just woke up to post for Yobit ,then it simply means they are financially motivated. Few of the spammer are already earning in this campaign. Feel free to read
[FABLE] The Resurrection of YoBit and tell me how many of the spammers are now thrown out of Yobit campaign for spamming .
