Google AdSense Template GuideEvery now and then, I get notified via RSS that I have a comment on one or more of my pictures, that I have uploaded to my Flickr account.

Just a few minutes ago, I received an update that I had a comment on the image on the right. The comment was very sales oriented, tell me to contact him to basically earn more than I can with AdSense.

To spam Flickr is not that easy. You have to register a Yahoo! account, find the images you want, and then comment.

I guess you can easily use the Flickr API to locate images you would like to spam with your commercial message and then send out a bot to comment at those images.

I don't think that those comments are nofollowed. But I did not dig deep to see if search engines can technically crawl the comments of Flickr images.
