A search engine reminds that links purchase doesn’t longer work and makes a detrimental impact on the positions of your resource in search results.
Recent members of Google team published in their blog an article about an increase of spammy links, which referred to as contributor, guest or partner posts. Usually these articles are made by a single site, but placed in other resources.

That’s why Google team recommend you analyzing the content you place in details, and think first if your target audience is interested in the material of the articles you want to share.
