Other admins also didnt see any rule violations in the comments you shared above. We simply dont have a rule against promoting Lemmy instances, in fact we encourage it because thats the best way for Lemmy to grow. If you have a problem with other instances, I suggest you talk to the admins directly, or alternatively block the instances so content from there wont be visible at all to Lemmygrad users.
