How to add Nofollow Attributes to a link?
It is possibile make a plugin? :D
All links or selective ones ?
I would like to all links by default and manage whitelist by plugin if possible...
I'm not an expert in SEO but I know that in XF all links (signature & topics) are nofollow from default. With an addon you can change those attributes. Why? It has some vantages?
None that I can think of apart from avoiding spamming links to be counted in the case a spammer is not detected in due time.
