Due to the evidence in this thread I tag 2 accounts, but I don't see it effective so far [at least for managers and campaign]. One of the [Jeway] users is still in this campaign and he gets paid weekly even though the evidence mentioned in this thread is quite valid.
Is it because my DT power is not convincing enough, or whether 1 valid red tag can't really prove anything?
Come on, mate. If someone doesn't have any problem attaching their brand to a neg tagged user, that's their choice. You have done your job by tagging the accounts. Did you tag them because you want them to be kicked out from the campaign? I'm pretty much sure your motive was to expose them as alt only. You feedback is still valid to expose them as alt. You don't need to be worried anymore I think.
