Comment spam

I am sick and tired of all the comment spam that clogs up this blog. Is it time for me to set up a captcha servcie or something similar?

The Akismet plugin certainly is no longer up to the task of keeping the new comment bots at a distance, so I need to do something. So far, I see three choices:

1. Leave it as is, and spend a lot of time cleaning up

2. Disallow comments all together, and loose the litle interaction I strive to build (I love comments from readers...it is those left by robots I dislike :)

3. Find a solution that enables people to easily add comments, and automatically keep the spam away

Option two is no option. So what I will do is go for option three, and until I find a viable solution, I will use option one - as it will continue to mess with my mind until I have found a solution. Or help me prioritize correctly, so to say.

Any and all tips and ideas are more than welcomed! I will write a post on what solution I choose, and why.

Thanks :)
