*At the request of a mod, I've made a separate thread about this.
So I recently reported to posts as spam:
viewtopic.php?p=16406777#p16406777
viewtopic.php?p=16386279#p16386279
Fris had recently ruled that a quote with no additional thought is spam, and many similar rulings have been made (notable to me, I received a warning for just that in my old nation "Benomia"). However, when I reported the above to posts in the spam thread, two moderators (Trans and Fran) said that it was not, in fact, spam.
To offer some other rulings, it appears as if a very similar quote that I reported here was deleted as well, although who deleted it is a mystery to me. There are many more examples from both sides but this is what I could find through light digging.
So I guess the problem here is that some moderators think that it's spam, yet others have said that it's simply expressing your opinion.
