Google randomly blocked my blog

Iv not been able to post much or even look at this blog recently seeing as I have been ever so busy... But it seems since I last posted my blog was deactivated(I don't know exactly when google decided to block my blog but its only today I noticed that I couldn't get on my blog or account). Well my account was deactivated for "unusual activity" and I had to verify my account using a mobile.... and then for some reason this made it all okay for me to start blogging again just because I provided google with my mobile number.... hmmm.
