Mark asked: How to batch deleting spam comments on a WordPress blog?

Mark just asked me how can he delete more than 6000 spam comments he received on his blog during his holidays.

First of it all, backup your WordPress database. Then, login to your phpmyadmin, select your WordPress blog database and click on SQL:
Batch deleting spam comments on a WordPress blog

Then, insert the following sql command:

DELETE from wp_comments WHERE comment_approved = '0';

All non-approved comments we be deleted. But instead of having such trouble next time, you should definitely install Akismet!

Oh thank god, I had one of my websites hacked via a plugin, forgot to reinstall Akismet, and was trying to figure out how to delete 32k spam comments. You’re a lifesaver!

I’m using a different template, so I think that is why this cannot be done.. i came up with the following:

Deleted rows: 0 (Query took 0.0003 sec)

Hmmm.. why?
I using a review type of theme.

Any other methods?

Got it solved.. My bad.. :) Choose the wrong database with nil comments.. sql is not that bad after all, NOT SO SCARY as i thought. Easy peasy.. :)
