The link filtering system is impressive, but it has some flaws that I believe can negatively impact SEO.
When adding a link to a website, the entire site allows that link to be followed by search engine systems. Someone with some knowledge of IPS (now IC) can exploit this and, even subtly, create harmful backlinks for specific sites (e.g., Site X or Y). This approach can lead to negative consequences.
My suggestion is to implement a system similar to WordPress, where I can decide which links should be followed. For example, I could allow follow links in specific content, such as articles in Pages, Blogs, or specific forums.
Additionally, it would be valuable to introduce a way to create temporary backlinks that apply only to a single post or thread, without impacting the rest of the site. The current system, which allows site-wide backlinks, should remain for other purposes, but for single-use cases, there could be a separate system—or a complementary feature—dedicated to managing one-off backlinks within specific posts.
While the current system is useful for certain purposes, I believe websites that sell sponsored posts or articles, for instance, should have greater control over this.
It would also be helpful to restrict backlinks to a specific link, ensuring that it can only appear once in a single article, post, thread, etc. This would prevent abuse and maintain a cleaner, more effective SEO strategy.
And how to do this? Very simple, when creating a topic/article/page/blog, etc., in the creation form, users who have permission can add backlinks for dofollow links in an extra field, so only that message or post will have the desired backlink.
