Freedom without boundaries is chaos. The yobit signature campaign and it's participants cross the line by engaging in spamming activities which is against the forum rules so irrespective of the freedom given to participants to wear any signature of their choice, they too have to obey the rules of the forum or risk getting punished. The administration of the forum took a drastical steps in banning members that had "one good report against them for spamming the forum while wearing a yobit signature" note they didn't banned all participants of yobit signature campaign, they did banned only those that disobey the forum rules (No spamming) and as a result of yobit paying those participants without an active campaign manager to moderate the campaign, they became an accomplice to spam so depriving them the privilege to advertise their product on the forum was the perfect punishment. I'm positive if they were to employed a campaign manager in future to moderate their campaign, the forum will welcome them back.
