Selling links violates the rules of Google, as it is an attempt to manipulate the issue. If you buy links for the development of the resource, then: eternal, so that search engines do not detect the “flashing” of links, high-quality, similar to natural ones, from donors filtered by similar topics and high authority, constantly, but little by little, so that there is no “link explosion”.
So the promotion will be safe, and the site will not fall under the filter.
