Some of the sites mentioned in this post belong to friends of mine who use WordPress not Joomla – However the same issues apply to those of us who run Joomla sites and choose to use a comments plugin.
My friend RT has written an interesting post on the pros and cons of dofollow versus nofollow.
His post sparked quite a bit of discussion on the issue and many commented on the large amount of spam that ensues when a blog is ‘dofollowed’. Frank Carr also pointed out that when he ran dofollow on his earn online cash blog his site was then picked up and added to various ‘dofollow’ blog list around the interweb – this in turn resulted in poor quality traffic and a deluge of spammers.
So what can you do? Well it seems the tide may be turning against dofollow amongst its stalwart followers, I have been a supporter but sadly reverted to nofollow a few weeks back – the spam was just overwhelming me. When you run dofollow many of the spam posts will be from real people, not bots, and spam filters have a very tricky time picking these up.
Akismet has actually worked quite well for me. I have a blog where I played with feeding RSS feeds into wordpress posts – using the wp-o-matic plugin.
I didn’t really check the comments on the blog for a few months as the project was just an experiment on something very different… But when I did look a couple of months later there were 900+ comments in the queue!
So I installed Akismet, which is a wordpress spam filter that provides a ‘check for spam’ button in the comments window. This scans all your existing, unapproved comments, not just the new ones.
Akismet moved all but 3 of the 900+ comments to the spam folder.
I did a double check by manually looking at 3-4 pages in the spam folder and they were definitely spam. The 3 non-spam comments were valid.
Akismet did a good job in this case.
If you are using Joomla this may end up being a major issue for you as all the comment components are 3rd party, and to my knowledge none have particularly robust spam moderation features.
Do let me know if you are running comments in Joomla and have any interesting methods to combat spam, has anyone looked at implementing Akismet for Joomla?
