I don't know if things have changed now in BTT, but at least some kind of follow-up of cases that raise some suspicion would be positive for the forum and for less experienced users.
No, you will not get banned for a scam!
It has been like that since the removal of the scammer tag and it will probably not change ever!
Also, for the reasons, a tiny difference, the time when each forum started, a lot of things at that time so prior 2013 madness where different, you didn't have these kind of scams as we do now and most of them were mainly because of deals between two persons so at one point theymos got bored of the staff team playing the judge and left everyone doing the judging for himself.
What will instantly get you banned on BTT is phishing links, malware and referral spam!
In its defense, there were a few cases that got tagged by a dozen accounts as a scammer and paid back the sum, or some that prove to not be actually a scammer and falsely accused, so to draw far fetch parallels , think of it much like the detach sentence in our real life world system.
Of course it fails terrible as users get tricked even by a guy who has three scams accusations on his profile, but..it is what it is.
I don't think a high rank account on this forum would do something like that. That is, it would be possible for someone to do it, but the consequences would be catastrophic for that user since their account would probably be blocked and their negative karma would be very high.
Yeah, another difference, nobody from the mod team will bother there if a high rank user has changed hands, before the merit system you could simply buy cheap farmed accounts, there were farms with more than 100 of them, all it takes was a bot posting every two weeks once and that's it.
And I don't think I've ever seen a discussion of IP logs other than when it involved serious threats to one's safety!
