Rules don't deal with scammers, they only limit the ones who follow rules.

this is absolutely true
bitter you are going to punish the one that commit the mess around than punishing everybody by setting new rule.

Better ban them if that is to be than, than causing trouble to everybody.
Petition was done, I think steemit inc will act also.
just like this scammer account that keep scamming and giving phishing links, that should be ban from here. Or let them roam freely
