I think that this would be mostly useless. The majority of the spam comes out of the altcoin bounty campaigns, and usually those "managers" just decide to pretty much accept everyone (without negative trust), without caring about quality. They could use SMAS, they could actually vet people, but they don't. I think that's the reason some decided to apply negative trust, as those bounties (usually) don't allow negative trusted users.

I don't really have a stance for whether spammers deserve negative trust, as I could argue easily for both, but I think leaving negative trust for managers/services who run campaigns that produce a lot of spam might be a better first step, as it encourages the managers/services to actually try.


One does not need to use SMAS lists to run a spam free/low spam campaign.
