Regulatory functions for our blog

Our blog, written in wordpress, is dedicated to environmental issues and is one of the centers for the formation of groups of people interested in solving environmental problems, has extensive international links and supports all global environmental projects. Blog articles are published by us, but we provide the opportunity to publish to all interested parties. In order to reach a larger audience with environmental issues, we have allowed the use of backlinks (trackbacks), and now a list of recursions that refer to our article is published under each of our articles. But the situation is such that the more time passes since the publication of the article, the less relevant the backlinks become and sometimes they are just spam. You must organize the ability to disable backlinks for articles, and our administrator should be able to select a specific time from the day of publication of the article, after which backlinks will be disabled.
