Anyway, the response to "newbie" grade users I am seeing here is unanimously negative, it is tough going. It took me an enormous effort to prove that an ASIC Seller website was legitamite back in 2019. I'll quit trying and perhaps come back when I have come up with a way to reassure I am not trying to screw anyone over.
Since you already have experience of this kind it's even more puzzling why you'd think that offering escrow services as a noob would work here.
This is a discussion forum. It's a very slow process to build up trust here so if you're looking to jump straight to selling trinkets and services you're probably better off on Amazon/eBay/Facebook, and if you're looking to scam - on Telegram. Otherwise stick around, get to know the place and the people and what they really enjoy and appreciate and you may be able to find a tiny niche for a tiny business.
