I received an e-mail about 30 minutes or so ago, that I've posted a new blog entry, even though i didn't do anything online at that moment. And after that it sent this message about my new entry to all my e-mail contacts (even though it shouldn't), including myself, many times again and again until i logged into WP and moved the post into trash. Was it just random attack or is my account hacked? Where can I get help on this topic and how can these attacks be prevented?
The blog I need help with is rmf555.wordpress.com.
