Spam Rapidly Increasing In Weblog Comments
dsurber writes "BBC News has a nice article discussing 'flyblogging', the phenomenon of spammers leaving advertising-related posts on personal weblogs. The writer comments: 'None of the other blogs I contribute to or run has been affected yet, but I can only assume it is a matter of time before the spammers move in, as they did first with UseNet and then with e-mail. It depresses me to think that any open medium can be so easily undermined by people with no scruples, no sense of responsibility and no idea of the damage they are doing.'" It seems a little surreal that people are having to develop anti-spam weblog tools.
Use the same type of human verification system that Yahoo uses when signing up for an e-mail account. If you can't type in the mangled letters in the image, then your post to the weblog is ignored. This would only be required for anonymous postings - if you're logged in, presumably you've already passed the human verification test upon account creation, so you don't have to go through the hassle each time you want to post.
Cyde Weys Musings - Scrutinizing the inscrutable
My hobbyist project was picked up by Google after a while, but it wasn't until I retroactively changed my comment signature here on Slashdot and on Kuro5hin (thereby creating many links to my project page) that it went to the top of the search results. It wasn't my intent to subvert Google in any way - I was quite surprised by the dramatic result.
There have been some less-than-scrupulous advertising companies in the business of that publishing dummy machine-generated web pages to exploit this trick. The dummy pages were typically filled with repitions of some nonsense paragraph, with self-links (to other dummy pages) and client-sponsored links interspersed here and there. The idea was that the self-linking would make the site look like a large, legit site to Google, which would mark it as relatively well-trusted and influential. Then Google would dutifully note the client-sponsored links and rank them highly. I believe Google has worked on ways to stop this; I don't know how successful they've been, or if the dummy-site makers are still around.
