Artists frequent this site so if they see that their recent content on kemeno linked here they change the links. It's happened many times.
And while I agree in part with the sentiment... this is not a reason to disallow links to search indexed places.
Links to Kemono have always been allowed since Kemono is indexed by google anyway. While we have rules about not posting direct links we cant control other sites.
Direct links to artists' Personal archives are discouraged as it gets noticed quickly
In the aforementioned post Kemono had already posted direct links so the poster had done nothing wrong and was being helpful by posting a link. he really shouldn't have been criticized for trying to give back
As I've already said... If Staff decide they dont want competing sites posted thats their call but currently there is no rule against kemono links... BUT they have pretty consistently been against posting artist's official personal links.
The rules are pretty reasonable as they are and allow for sharing without too much exposure. Personally i wouldn't want to restrict what works so well already.
