[Borderlands 2] How does everyone know I'm a Vaulthunter?

So I'm an adventurer that came to Pandora for the sick treasure that is apparently hidden somewhere here. Sure, i have some cool powers that most people don't have, but otger than that i look like a pretty regular dude. However, the second i arrived in Sanctuary, which seems to be a relatively safe place, people greeted me, they even treated my nicer because "I am a vaulthunter." I even watched one guy dying, and all he spoke about was how he is impressed that an actual vaulthunter came to save him. So my question: what is it about me that makes it so easy to tell that i'm not a bandit?

1: Most of these communities are pretty small, thus they know each other fairly well. Only a complete badass can travel from town to town by themselves, as EVERYTHING can and will try to kill you. Such badasses tend to be either Vault Hunters or from Elpis.

2: Vault Hunters tend to bristle with weapons and gewgaws. Not counting the stuff you have in your SDU, you'll probably have about 3/4 guns openly displayed. Said guns tend to be strange looking, as most run-of-the-mill guns do not work for Vault-Hunters (Tediore excepted, as they are so cheap, they are literally throwaway guns)

3: You probably have some unique thing about you. You might be carrying a portable turret, You might be able to dual-wield guns with little to no difficulty, You might have Siren tats. You might have a pet Rakk/Drone. You might have a throwing shield. Point is, the majority of people don't have these. They mark you as something else.

4: You can use New-U stations. This isn't something anyone else can do.

5: You get strange gifts from something called "SHiFT".
