Captcha and wordpress saved my blog
During the wild neglect i've had for my tech blog, comments have gone AWOL crazy... i'm talking 10k plus comments of spam. To prevent this, I installed and configured captcha and deleted ALL comments in moderation (sorry!).
Because there is no good way to bulk-moderate in Wordpress, the thread below shows the query I ran to remove the 10,000 comments.
Then, the captcha addon can be downloaded here:
Very nice! Blog is usable again!
