This is solely my opinion as I'm not familiar with the Discourse software in regards to its structure and guidelines. But thanks to this topic and more importantly thanks to Slant as well, I am curious to learn more about it and wouldn't have been as curious if it weren't introduced to me in any other way. However, after doing a bit of reading on the discourse site (and the meta section) for the purpose to understand how it works, I coincidentally ran into the same exact post that @Cawas shared a link on
Which then lead me to search more about the topic of being able to link back to Slant.co from the meta.slant.co site. To sum up from what I learned while going through the posts on their site, I understood that it's much more complex than I could've ever imagined. After reading @StuartK reply
My first assumption was that it was restricted only for SEO purposes. Although I'm still unsure exactly why it's as big a deal as they (Discourse Meta) make it seem to be, or if I'm mistakenly understanding they're meaning as referring explicitly to the use of having a backlink or linkback within a site for SEO. But my current conclusion to what I understood so far is that @Cawas found and referenced exactly what my intent was when I asked about adding this to the meta.slant.co site.
Also, from the same post that is referenced, shows that this is a very common and specific concern for several users. So, I believe it's the best solution and I think that post covers all the necessary info needed for doing this, including being the only source to be used.
