Frequent CPU Exceeded Message
I realised there’s alot of CPU exceeded message on my blog lately. I was looking at my logs and found some weird entries from the IP address: 62.163.80.205, so I went to do a google, and this was what I found from projecthoneypot.org:
The Project Honey Pot system has detected behavior from the IP address consistent with that of a spam harvester. Below we’ve reported some other data associated with this IP. This interrelated data helps map spammers’ networks and aids in law enforcement efforts.
If you’re interested, you may click on this link to go to the projecthoneypot website to check it out yourself.
These automated spammers and harvesters repeatedly loaded webpages on my blog, causing the server to go down. I’m in the midst of trying some tactics to track down the IP addresses of those harvesters/spammers and blocking those IP address from my site. I just banned over 50 ip addresses from my site. Hopefully, this will cause less errors.
I’m so sorry that my blog has continually gone down these couple of days. 
From my logs, it’s an unprecedented case. I’ve been attacked for the past couple of weeks, and especially the last few days. Rest assure that I’m trying to keep on top of things. In the meantime, I seek your kind understanding if you visit my blog and found it down.

I don’t know what plugins you’re using right now, but I find the combination of WP-Cache, Bad Behavior, SK2 and Akismet to work well for me.

Hi Elia,
Thanks for the advice. I’ll check out those plug-ins. I’ve been using Akismet, but Akismet doesn’t stop those bots from sending repeated HTTP requests. It’s the repeated requests that knocked down my server because it causes overload on some of my scripts, e.g. my stats script due to excessive calling and writing to the SQL databases. So, I need to try and block these blacklisted IP address from even visiting in the first place through the .htaccess file.
I’ll probably augment those plugins with the Project Honey Pot thing that I wrote about. I’ll be creating honey pots on my server as part of my contribution to fighting these guys. Do give Project Honey Pot a read and consider helping to indentify these harvesters and spambots!
