We can only guess who would like to join the 1xbit signature campaign. If everyone gets a red trust automatically, we won't find out, because no one wants to spoil their account and prefere make safe money from other campaigns.
Why would anyone in their right mind want to promote a proven scam? Do you honestly believe that all people are this corrupt?
The accusation of scam is based on complaints of users. 1xbit claims that accounts of this users have been blocked because of cheating. Unfortunately, this is a word against word and neither side gives conclusive evidence. Whether it is a scam or safety action of 1xbit security team depends only on who you believe more.
