Ah I never saw the platinum account advertised, i’d recommend some sort of message promoting it as users sign up because I may have actually gotten it straight away at the time.
I mean for me personally I registered because I saw an x7 for £25 here, and in the end I found the seller on Facebook quite easily (sadly I can’t get it as I have a wedding on the one date I could have picked it up).
In that specific case I would have quite happily arranged to pay in full and then trust the seller to actually provide it but of course that doesn’t work so well for a £500+ marker.
Maybe there could be something with asking people to upload a photo of their id? While there isn’t much it can do in the way of truly preventing someone scamming others, it’s pretty much the same concept as a lock, keeping honest people honest.
Just an idea of course, the only reason i’m particularly against these post limits is back when I played years ago as a kid someone on a forum with this system in place stole my x7 when I paid him to repair it anyway, so it didn’t do much in terms of an effective deterrent
