Yeah, look at this link here as it relates to their ToS: Account suspension FAQ - Gumroad Help Center
I was livid, I cannot believe they have something like this in place. I’ve heard such good things about Gumroad too and they make it super easy to sell what you want and get paid.
And I agree with you @PROTOFACTOR about putting your assets out there. But other than Gumroad and Sellfy, I don’t know where else to put my product to sell while waiting for UE4 marketplace. I have put myself out there on social media and YouTube and created my own website, and I have driven a bit of traffic to Gumroad and Sellfy, but it does seem that a majority of people want the ease of use of the UE4 marketplace. I’m the same way as a consumer, having the products right there in the Epic Launcher is helpful. Plus, my current product is really UE4 only so I’m kind of limiting myself there.
