The user is offline since 17th July 2023. If participants of the campaign still hold the signature doesn't mean they are getting a weekly reward as they have no/will have no alternative way as they will not be accepted on any other campaign. As they cant join on other they may promote the scam voluntarily.
But is their no possibility of paying their scam promoters without coming online here to mark the spreadsheet of participants? As I finds it very unusual for someone to be promoting a scam project without getting paid, not even a project or casino that have good reputations that one could have said maybe it's done just because of the good name.
And secondly if they are not getting paid why not just remove the signature from their profile, maybe they might get some mercy and the tag on there profile reduced.
