I just tried to access this site and received the error message from my webhost that I’d been using too much CPU and the site had been suspended.
Looking at the error logs, I see that I can probably cut down on CPU usage if I discourage spam commenters a bit more1. So is there an experienced WordPress user out there who can recommend the best way to do that? It’s not spam filters I’m looking for – it’s something to stop the spammers being able to post at all. I tried implementing the plugin “Did you pass math?” a while ago and it seemed to stop genuine commenters as well as spammers, which wasn’t the intention. I don’t really want to restrict the ability to comment so that only registered users can comment. But if I have to, I will. Any ideas anyone?
I’ve also switched on the WP-cache plugin in the vain hope that will reduce CPU usage.
Any other bright ideas? If it helps, I’m with Bluehost (using their basic package), and I’d rather not move for the second time this year, or fork out more money for a virtual private server (my advertising revenue is still lagging behind even the cheapest webhosting charges). Thanks.
- would you believe it: since I moved to my new webhost three months ago my stats tell me I’ve received TWO HUNDRED THOUSAND spam comments – that’s 2,000 a day
