Don't believe in anything that he says.
He has zero reputation on the forum. He's trying to get you to contact him off the site on other communication channels. He's got a self moderated sales thread on the forum to avoid any victims from complaining on his thread as well.
Never deal without escrow in these cases, when people are trying to sell you any sort of good or service of substantial value. You simply can't take their word for it.
The amount of youtube and instagram followers are absolutely irrelevent when it comes to his trustworthiness. The fact that he doesn't accept escrow means that he's got something to hide. All legitimate members of the community, even the most trustworthy ones, will accept escrow if you demand.
