It seems 1xbit are very happy to
work alongside these types of highly dubious (at the very least) characters.
According to this spreadsheet All the participants has atleast one negative trust what I can see by default trust view.
I have reviewed all the accepted participants and noticed all the participant have at least2 negative trust from default trusted users. Anyway, the users who had joined on this campaign knew they will get negative trust and even they may get banned for promoting 1xbit like promoting yobit.
