[I'm assuming no, but don't think I've seen it explicitly addressed, in which case this can become documentation.]
New user @yasyf is repeatedly posting links to a certain payment provider. (6 so far.) I've already inquired re: disclosure, but the posts also include a discount code. While the links to the site are non-affiliate, there's no real way to verify that the discount code doesn't have the same ultimate effect, and they probably don't belong here regardless.
