I’ve just changed from using wp-blacklist to keep the comment spam in control over to WP Hashcash. wp-blacklist was having hassles with comment spammers leaving (intentionally?) bad urls, which were getting put in the blacklist and then causing wp-blacklist to choke on any comment input.

Wp Hashcash looks great so far. I’ll report after a couple of weeks.

But don’t get me wrong. wp-blacklist did a great job for a long time on my three blogs. I might well end up going back. Who knows? But we have to try out new things….

[Update 16/1/05: I've reverted to wp-blacklist. Something in WP-Hashcash was causing some looping in php, leading to apache processes on the server eating up all the CPU time. More on this when I work out why....]

[Update 29/1/05: I tried a manual installation of WP-Hashcash and it works without running the CPU into the ground. Good. ]
