What one perceives as spam can be subjective since obviously different audiences react different ways to certain subjects. From a Wikia-wide, Terms of Use point of view, "spamming" usually refers to posting for the sole purpose of advertising a product, not in terms of a neutral article about a product per se.

Local wikis may have a more strict policy about what constitutes spam - the "don't post links to outside wikis in chat" example fits in here.

Communities are welcome to define their own policies about what is spam and what deserves a local block, in so long as the policy is not allowing something explicitly banned in our Terms of Use.
