I hope not...I am using "Official" for one of my forums.

Although, I think it may be possible, because if every site decides stating they are the "Official" whatever in a field, then a bot may consider it spam, and completely ignore the word.

Bots are also smarter now, and even if you are stating you are the "Official" authority or site regarding a topic, then bots for no reason at all won't just ignore the word. They will take the word into account.

IF you are claiming to be the "Official" site for Britney Spears, that may bring problems I think, as you are not the official site for Britney, unless SHE or her company etc created it, and so a bot may have better judgement and consider the word "Official" in your title as being irrelevant and completely skipping it.

I can see that happening to help filter spam for bots, but other than that I think its not really a big deal.
