If you look at people's promotion of the 1Xbit campaign, you will see that they are people with a reputation or any high that is well known in the forum. All the accounts that have been seen promoting the campaign are not active accounts; they only wake up and apply for it, and they were picked and continue to prompt a well-known scam project that's not right. However, if you look at them well, you will see that all those accounts have neither negative nor neutral trust in them.
Have been consequence for user promoting the scam campaign will receive negative trust with their account, actually many board had explained about which one scam gambling side and consequences receiving is the user keep promote the scam campaign. All account had promote the scam campaign such as 1xbit get red tagged account but its not including with that campaign promote only for all campaigns. Likely this scam gambling site still active right now although not promote with bitcointalk forum because I found on social media platform twitter make new tweet every day. that's right, there are also many signature campaigns running here that become scams in the middle of the campaign, not before the campaign takes place, if a scam project is going to hold a signature campaign then there will definitely be many DT teams who will give warnings and even give red flags to the project. just look at what happened to the gambling signature campaign that ended in a scam, there are definitely red flags all over the account.
Seems exceptional with the campaign running in the middle way get scam and the user can't category as promote the scam campaign since know the campaign have been scam stop promote it and remove all signature code or avatar in their account. Can't predictable with the project will the project ended become scam or not but the OP points about promote campaign have been scam in the first time not running in the middle way.
