I believe that the widely-accepted definition of "spam" is when one posts/sends messages that have no relation to the topic at hand, a post/message that is pointless and wastes space; often seen on imageboards, forums, or in e-mail accounts. Not to be confused with "flooding".
Unfortunately, I have to agree with you on the point that I made myself look bad; I however do not enjoy jokes when a topic (no matter how bad it is; as long as it's related to the sub-forum) addresses a rather serious problem as there are arguably broken Pokemon already in UU, but I'm not one to suggest quick-bans. I know that testing is generally best for an unfamiliar metagame, but there are just a few Pokemon that people know deserve to be OU based on their stats/movepool/ability, i.e. Chansey.
