I woke up early today and found that all my sites were down and they are still down because my webhost has suspended my account due to CPU Overloaded. I had been googling a bit and read that the culprit is the cron job and also coupled with cheap hosting that shut down the system.
After some further reading, I learnt from several support tickets sent to WP Support that a few people had experienced the same thing and one of the suspected plugin is the Bad Behaviour spam filter.
Last night I also noticed that MyWomenBlog had been giving me 500 error on and off and two of my posts went missing. On top of that, I noticed that the auto-save also produced different posts and kept it on the dashboard. I.e. If I take a while to write a post, I will end up with three posts being stored in the Draft on my Wordpress dashboard. Shit, I am so sick of these.
