the next alt-account made by a scammer, and it's obviously a scam waiting to happen. But technically he hasn't "scammed previously" until a victim shows up.
its obviously acceptable if you have alts accounts here not unless you abuse bounties,and having alts account doesnt mean you will abuse bounties,you're perfect example you are using your alt when using mobile,theymos when hes away the point is do not shoot now then ask questions later.If the alt was from a known scammer of anyone who scammed previously then his alts should be tagged like what his main account have.
i have ideas,
Red tag for account sellers/scammers/
Gray for alts but it wont be highlighted on every posts like what in red tag is will serve as indication that that/this are alts of someone else.
Merit abusers? like what we have in alts,gray..cause if you have alts its morelikely you will merit your own alts... its always together.
Orange for suspiscious account that might scam but i dont agree with this because it will lead to another abuse.retaliatory feedbacks will morelikely be used.
Sellers/Scammers and other shady things should be red tagged and highlighted to the profile and each posts..below the signature.
