Been a while since I'd checked the rules so maybe it's been changed for a couple of years, but I do remember it saying at one point that you could post as a seller so long as it doesnt link to anything (And maybe it couldn't have the same name? I can't remember the specifics)
Edit: Found an
where they say
"We will also remove posts that run counter to our culture of true exhibitionism. If you sell stuff (panties, cam sessions, etc), then you may get blacklisted by us. Please use a separate account to post here (with a completely different/unrelated name), such that there is no economic incentive to your participation."
So a seperate name would be required anyway, but the rules were once different and allowed sellers so long as it was a seperate account with a seperate name
