Just because a person makes a bad decision, does not make them intrinsically bad, or even a scammer for that matter. [1]
Yes aTriz made a mistake[2] by continuing to manage a campaign when he knew there was some shady business going on[3], but just this information, in and of itself is not necessary evidence of a scam[4], 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[5].
It's funny how quick to turn people are[6], 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[7]. The fact is aTriz is no longer managing the campaign once it came to light[8] 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?[9]
[1] This applies to hundreds of others who have been negged for one single issue and will never be given a second chance.
[2] I really like to see flexible excuses.
[3] Not just was he aware of it, he actively participated in it.
[4] How many scams does qualify one to be labelled as a scammer? Ans.
1[5] Did he make the offer upfront or after being publicly accused of it? I believe he would have done nothing had he not been called out for it. Also I think (might be wrong) @snakey was in Chrysoscoin and this is Bitblisscoin. If you consider Chrysoscoin to a scam in which Atriz was complicit, this makes his
2nd scam.
[6] Who turned on him? Are you hinting at those who changed their ratings?

[7] He definitely knew that they were lying and that he was complicit, accessory to it.
[8]
WRONG AND GROSS MISREPRESENTATION; Atriz stopped managing it after he was called out for it and admitted to going along with the lies; it wasn't like he stopped the campaign the day he was asked to lie.
[9] This is a totally rational route to take, people who will deal with this account in the future should know what he has done in the past and as members have rightly pointed out that Atriz has stopped responding to these and has not even tendered an apology (not that it should change his neg), he simply wants to ignore it and move ahead, also what would you suggest to make it right?
P.S. Did @snakey get his investment back?
P.P.S. Are there other claimants as well?
