This is not spam.
It is a way to point out a too common behaviour on these forums using a joke. Saves words and explanations, gets right to the point, attracts attention and as a by-product provides the opportunity to identify forumers with no sense of humour or self derision at all.
I feel ashamed to have to debate it though, but better me than Spankmeyer having to ruin his own post by explaining it.
I personally found it funny and to the point, thanks.
