Google Image Labeler is a fun game people can play to help Google Image Search better understand and tag pictures within the Google Image Search index. This game launched in September 2006 and has been somewhat under the radar since then.

Recently, I saw not one, but two different threads in Google Web Search Help forums by two different people, who both spotted pornography in Google Image Labeler. One even saw child pornography. Here is what they had to say:

Is there a way to report images that are offensive or inappropriate in Google Image Labeler? No, not really. You can in image search, but not here.

Forum discussion at Google Web Search Help.

Update: Googlers have replied to both threads.
