Some time ago (it's been 2 years already) I've created a wordpress blog on their domain. I had some reasons at that time, like wanting to test their product and having some fun writing there also. I have not posted there very often, only when I remembered about that blog and when I had the time for that operation.
Earlier tonight I've got the first and only error message I've got on wordpress until now: account suspended. I never suspected that could happened, I've done nothing bad lately (as I know it) to trigger such response. I accessed the wordpress support (over here: en.support.wordpress.com/suspended-blogs) wondering why that happened. I still don't have and answer, but I solved the problem very simple: I asked for a new password (of course I did not loose or forgot it, but the system does not know that). After I changed it I accessed the blog easy.
