I believe the first one refers to the topic's title.
Well, forgive me on that one for seeing the idea that every-one posts a single number.
This is not a "longest thread ever!" thread, he is simply challenging us to count.
Numbers go on for a long way. If this continues, it simply is just posting for as long as possible, with numbers.
He did not declare this a spam thread.
That doesn't change the fact that it is completely pointless and only asking for un-intelligible one-number posts. As far as I'm concerned, that's just spamming in a topic, which in it's own rights was designed purely to be filled with this 'spam'.
