I do believe that the accusation here is that Edwardard ran a campaign that wasn't sanctioned by DMarket and that some of the signature code (?) contained malicious code.
I've checked the signature code, unless altered later (or unless I did miss something), the links seem to be genuine and leading to the correct sites.
If the whole basis of this accusation is that Edwardard ran a successful campaign advertising DMarket that wasn't sanctioned or funded by DMarket,
then I don't see any scam happening here, especially not from the side of Edwardard (the hidden runner, the one who hired them could have disclosed they aren't running an official campaign).
I see this similar to eg me hiring aTriz to advertise my affiliate link for CoinBase via a signature campaign. Everyone gets paid and the campaign completes.
Would this make either me or aTriz a scammer? I don't think so.
Well I read everything here and for me there was no scam. Edwardard is a honest campaign manager and this is the first scam accusation I've seen against him so far.
