I don't really like the bandit identifier idea and I'll use myself as example to explain why. Generally (there are exceptions) I do tend to KOS armed people, especially in the north. This behaviour would certainly give me a bandit identifier, but I don't kill unarmed or backstab/betray people. I can be friendly too at times and have patched strangers up. But if I'm classified as a bandit, no one will interact with me or believe my good intentions because they see me as a scary bandit. They will just shoot me on sight or run/hide. Scenario 1, with bandit identifier: I've got bandit skin. Someone sees me entering a barn and will shoot me on sight, because I'm an evil "bandit." Scenario 2, without bandit identifier: I've got survivor skin. Someone sees me entering a barn, but instead of killing me he decides to risk it and starts chatting, saying he's friendly and asking if i'm too. Considering he could've already killed me, I tend to trust him. We could go on and have epic adventures together. I won't betray this guy, even if he has better stuff than me. tl;dr: I don't believe everyone who likes a bit of PvP is always 100% bandit 24/7. At least I'm not. But the bandit identifier will make strangers think I am. That means even less group play and more PvP.
