That's kinda why when new members join, they have to climb the theoretical ladder of legitimacy. I don't consider you trusted, but that doesn't mean I shouldn't deal with you. There is always a user online who can middle man, it's users who rush the deal who end of getting scammed a lot.
On the flip side, just because your a new member don't let a more experienced user take advantage of you. Check their profile out, check if they have a scam report(s) on them, as well as check their vouch thread if they have one. Use a MM, whether it be a staff member like Goon ( bend ) or a trusted user who you can do the same steps I said for checking out the seller. Be smart with purchases, don't rush them.
