Scammer - Claims to be a mod

I was messaged by this guy looking to buy my PSN account for sale. He, then messages me on discord using a discord account that goes by: SaltnVinegar#9210.
He proceeds to tell me that I should trust him because he’s a mod, and that he doesn’t trust me, when I’m the seller. I give him the option to use a middleman, but his response was that he doesn’t know how to use a middleman, and then backs out of the deal saying he doesn’t trust me when I offered a middleman service...
