Hmm, this is interesting... I have never heard this before (I guess I never read the terms carefully

)
Here are my 2 cents... I wouldn't worry about it. I am guessing that it is incredibly rare if they even still do that. It may have been an old "disclaimer" from their start-up days, but I don't know that for sure.
If you really want to be 100% sure, you can host your own Wordpress blog (you will have to subscribe to a host, buy a domain, and upload the Wordpress software to your host).
Hope this helps.
