Did you see the Red Trust I left them in August? I'm not DT, so you have to click "Untrusted feedback" to see it. My complete list for this person: 10 Alt-accounts of the same person: Gustavv, BtcGreen, Comvuse, Revolutioner, Seven Up, Magicrush, AikoniA, MasoVa, Kasawari, kompeni.
Fromt his list Gustavv is in your campaign too. I'll leave it up to you to verify, that account never complained to me, and after being blacklisted he never posted again in the giveaway that I manage.
After this list of 10, I stopped giving Red Trust, I now add them to my own local list. It saves me time.
Damn, should have checked. Earlier didn't had any rule on disallowing alts. so took things lightly. Its just now that I had changed rules to check on these users. I however didn't find anything against gustaav, though I was also suspicious of him and one user more.
