I actually wouldn't have noticed them if you didn't point them out. I actually agreed with them until they started with "Two And A Half Men is well written", that's just spam...
But no, you're just meant to report it and ignore it. I still remember good old ForexBest (or whatever it was called), first spam to ever try to scam me over PM. It was slightly annoying but it did show me how easily some community members were confused by it. I really think there should be some form of "Spam Report" forum to alert the community of spamming profiles until a moderator can deal with it to prevent confusion.
I wouldn't worry about posting in the topic though, it was a simple mistake, the mods here won't lynch you for little mishaps, just make sure not to make a habit of it.
Actually, the main part of the text focus on the title in the "topic name", with the "DVD"-links(it is probably a bad idea to follow those links)squished in.
I think it was the Big Bang Theory it was actually referring to, by that logic.
But i reacted a bit like You myself:
How can they place Two and a half ... among those, and say it is well written, even?
But i didn't consider it spam until i noticed that it actually was commercial-like, had irrelevant links squished into its own line of reasoning, and was totally irrelevant for the forum it was posted in.
(I'm fairly new on the 'net(summer-autumn -09), so i haven't encountered this kind many times yet .....)
And when i looked at the Community, and saw another, i became certain.
