Just because a person makes a bad decision, does not make them intrinsically bad, or even a scammer for that matter.
Yes aTriz made a mistake by continuing to manage a campaign when he knew there was some shady business going on, but just this information, in and of itself is not necessarily evidence of a scam, at best this could simply be evidence of shady marketing tactics. To discount the dozens of other campaigns he has run successfully, and his attempts to make this right by personally refunding snakey shows that he is at least worthy of a second chance.
It's funny how quick to turn people are, yes aTriz was wrong to promote an ICO with the knowledge he had, but at that point nobody knew if the ICO was a scam. The fact is aTriz is no longer managing the campaign once it came to light indicates that he had no intention of promoting a proven scam, prior to this, it wasn't proven, so why is he being negged to death?
Wouldn't it have been more logical to tell aTriz how to make this right, rather than going this route?
This is not the first time aTriz has shown extraordinary naiveté and disregard for common sense.
"Proven scam" is a meaningless criterion. Most scams are technically unproven until the scammers run away. aTriz had information that indicated the ICO was shady at best and he brushed it off as a marketing strategy. He needs to rethink if he really wants to have his name associated with such projects, not to mention the impact on other users - I think it's inappropriate for a green-trusted member to knowingly provide undue legitimacy to potential scams.
