I have - I play about two videogames a year, stickign to things that are rated 97% by most magazines (ie, the few that are really worth playing). Looking for BioShock info I ended up at an original-content-free Mahalo link page.

Either have I honestly, and I am certainly not one to join a private army simply because I am told to (this isn't 4chan).

Unless I see legitimate proof of them "spamming", I'm not planning to report then. People who are affected should, but honestly, there are plenty of spammers/scammers out there. Many are probably more important than these, and I'd rather that Google removes links for fake banking sites and such first, than a website which doesn't even have a bad "web of trust" scorecard.

Reporting Mahalo is more about the fact that they can get away with search engine spam in front of the public. If we use this way to report them, there is absolutely no way for Google to turn a blind eye on this.

their success is in the long tail, not on actually reasonably popular search terms.
