I was specifically given the go-ahead by a ROBLOX staff member before I posted this. Moreover, I’m not the first to offer or sell for USD. Morevoer, here’s an instance of ROBLOX staff encouraging selling assets for USD. If I’m in the wrong, so are all of these people, and the rules should be made more clear and enforced on here, which has not happened yet so they’ve been implicitly giving the go-ahead.
Edit: Whoops, linked the right thread but the wrong post on that last link. Fixed it.
