Besides I don't agree with the "beyond reasonable doubt" as if this was a murder case. So. If there's a lot of evidence but there's 1% doubt you're not going to red tag him?
Even if its 100% a purchased account, I don't issue red tags for that -- at least not as the sole reason for issuing a tag. I don't mind so much if others do, but its just not something I personally do. If its a bought account used for nefarious purposes, like scamming or promoting a scam project, then I would red tag the account, and probably mention that its a bought account in the feedback.
I'd sooner attempt to link them to other accounts and then bust them for campaign cheating, if that's what's going on.
If red tags are being given - for whatever reason - I think the provision of conclusive (or at least strong) evidence is necessary.
It seems like you have a wiser outlook for now. I thought you would red tag it. OK, looks good and hopefully the account isn't used for fraudulent activities. However, in my opinion, the account was only used to participate in the signature campaign
Give him 500 negative, why bought account, broken rules of Bitcointalk. If I Dt, no one would safe. be brave , come on guy
You can give him a tag if you want, Or use your main account to tag him
