If true, the traffic increase presumably results from increased media attention, raising awareness of the site, causing new people to seek it out, adding the court-ordered block to the long list of examples of the "no such thing as bad publicity" phenomenon.
Item the second: A series of self-congratulatory articles on Digg about the recent anti-Scientology raids and protests by Anonymous (yes, yes: we are legion, we do not forgive, we do not forget, we are your waiters, we have seen Fight Club too many times), culminating this weekend in a series of coordinated global real-world protests.
Exercise for the reader: Assume that Anonymous eventually gets bored and switches targets or otherwise moves on. Once the dust settles, what will be the long-term impact on Scientology: Net gain, or net loss? Show your work.
Is Scientology a deserving target? Of course it is. And this is not a new thing -- the anti-Scientology fight has been going on for years; remember when Usenet was the big battleground? But to imagine that this is for some higher purpose than lulz or notoriety or whatever is just silliness.
