Since that is what "promote" and "promotion" can and does mean then yes, provided there is a possibility of discussion and nothing saying not to then it is promotion. As I have stated - threads against this part of the rule are ones that go out of their way to not want discussion or specifically state it only wants one word or "pointless" threads, or lack any "serious" discussion which seems to be the impression I'm getting after reading the spam forum threads. Threads like "WELLL???" with no quality other than that as the thread title and no post that can easily allow you to understand what the point of the thread is may be against the rule (if the thread doesn't appear to evolve or later on the OP makes it obvious it hasn't got a point). Moderators can leave it for members to argue what the OP means: "I am well thank you", WELL??? what? :P" etc. If the OP says "Just bored and making a thread" then the thread is clearly in violation of the rule and if I recall correctly moderators just move this sort of thread into spam to die or to allow to carry on as a random discussion thread with no actual topic. It's a "do as you please" thread, rather than a "do as long as it has a topic" thread.
This thread looks like one example where it was posted somewhere else and as it served no purpose in the forum it was posted in, it was moved to spam.
