My own bot traffic can be anything from 30% to 60% of the total, and the trend is generally upwards. I knew they are a nuisance, but I was gobsmacked by Brett's figures. If this is the shape of things to come, we should all be worried.

Some people have mentioned CAPTCHAs as a way around this. It probably won't help WebmasterWorld for the reasons Brett has mentioned. But I've been considering using them in on some of my sites. What worries me is how to make them accessible.

How can you have a good CAPTCHA that doesn't exclude users with vision problems? I often wonder why I've never come across a site using sound files as an alternative CAPTCHA test.

Anyway I wish Brett the best of luck in dealing with this issue.
