Matt Cutts has his annual post on tell him what Google's search quality team should tackle in 2009, to prevent web spam.
So far, Matt's post has 90 suggestions. So if you really hate web spam, go there, comment and let Matt know what you think. Matt said:
Based on your experiences, close your eyes and think about what area(s) you wish Google would work on. You probably want to think about it for a while without viewing other people’s comments, and I’m not going to mention any specific area that would bias you; I want people to independently consider what they think Google should work on to decrease webspam in the next six months to a year.
Once you’ve come up with the idea(s) that you think are most pressing, please add a constructive comment. I don’t want individual sites called out or much discussion; just chime in once with what you’d like to see Google work on in webspam.
Okay, so again, if you hate spam, go to Matt's post and comment.
