What distinguishes the bbs network from the sites Facebook?

What distinguishes the bbs network site from the rest of the other social networking sites is that no matter how many links you put, the bbs network publishes the content that it broadcasts among all users, unlike what happens on “Facebook”, for example, when you publish links to external sites in your post, the Facebook algorithm blocks this post More your followers than your regular posts so that Facebook users stay on the site and do not leave it, so the chances of them seeing ads increase, which contributes to increasing Facebook profits
