According to the new flag dialogue, spam:
Exists only to promote a product or service, does not disclose the author's affiliation.
While before it was:
This [question/answer] is effectively an advertisement with no disclosure. It is not useful or relevant, but promotional.
Now, for most spam posts, this does not make any difference, but sometimes you have a post which only exists to blatantly promote something that is not a product or service, e.g., a world view.
This question on Academia seems only to exist to advertise an advertisments-are-evil point of view. (Note that this answer is also blatantly off-topic, but that’s not the issue here.)
This answer on Physics seems only to exist to promote some paper that the answerer likes. I successfully flagged previous similar posts by the same user as spam before the rewording. (The publication is also very far from the scientific mainstream (to be mild), but that’s not the issue here.)
My question is: Should I still flag those posts as spam? They abuse Stack Exchange for publicity, which is precisely why are so keen on hitting spam and spammers quick and hard and in particular harder than just (closing and) deleting the posts. If I should not flag them as spam, what is the ideal course of action to take?
