Unless the scam is being promoted on Bitcointalk, I think it's pointless to warn people here against random site X. People who visit the scam site through external links won't see the warning, and people who see the warning weren't going to visit the site in the first place.
I am of the opinion that if it is scam bursting and crypto related, since it's not causing harm to the community it shouldn't be discouraged.
Scammers have related strategies, once bursted here can be related to others not in the community, then that particular strategy and its likes would be defeated.
