> And is a Wordpress-hosted blog truly anonymous?

Would not be surprised if someone figured out how to register a free Wordpress account to the point where any disclosed information is a dead-end trail to any corporate investigators. Takes a dedicated discipline and tradecraft.

If I was in the shoes of OP I certainly would not be discussing anything related to my case until either its conclusion or with all publications reviewed by lawyers.

Then again I have not been in this situation but have seen how things can go south when certain advice is ignored.
