A problem in the past for many people was that the report spam form at Google never worked. But with Matt Cutts and his team now devoted to squashing the spammers, it seems like Matt has stepped up this process and are manually penalizing sites at a rapid pace.
A Cre8asite thread named Spam Report Works!!!! accounts for several members reporting quick action on Google's part with the submission and removal of spam.
I reported him to Google with the spam report link and today I checked to see if he was still there and he's definely gone!
I reported a spam site and labeled it 'jagger2' as matt c suggested... in the past they never worked - this time, it worked w/in the week.
Yep, they're really quick about it at the moment.
The thread kinda turned into the debate as to its a good idea or not to report sites as spam. But I won't get into that in this entry. :)
