This is my second time that my 2 wp automatic blogs got suspended by HG due to the same reason "high server loads" These blogs are running under HG's shared hosting server.
I am using "automaticblog" wp plugin and it was set to 1 article a day but still got screwed up. So, for those who are autoblogging lovers please be aware of this issue if you are using HG shared hosting.
If you are posting more than 2 posts per day I recommend you to install WP-Super-Cache plugin which helps to greatly reduce the CPU required to run a wordpress blog and can help you to have more traffic while using less CPU. It's free.
