Yes, but there is one more point that users of 1xbit won't be accepted in any other campaigns because of their trust ratings. Due to this, these people won't care to change the signature.
However, to confirm if this is the end or not, we can check next week, if the 44 weeks gets updated or not from this spreadsheet.
Participants on the 1xbit campaign average redtrust rating accounts so they apply on the 1xbit campaign because the requirements do not exclude redtrust accounts. The campaign is still running although there is no specific date for the weekly schedule in the spreadsheet but many users are still actively promoting this campaign.
They will continue to promote as long as they're getting paid.
But I wonder why some of these participants (Edrogan specifically) are not active anymore posting in this thread. Because I used to seeing them defending 1xbit for all the accusations.
