Is Blogger easily hackable?

I hadn’t checked my old blog at Blogger for a few weeks and when I tried to log in to Blogger yesterday I found I couldn’t access it. They now consider my blog a spam blog and it will have to be reviewed by a human before they can restore my access to it. WTF, I thought, and proceeded to check the site (I won’t link to it, you can guess if you really want to or maybe you remember for some reason). Indeed, it was filled with porn advertising and my content was gone. I’m not sure what will happen next, but for the moment I’m locked out of my blog while it’s displaying porn spam. All I can do is remove links to it from wherever possible.

I’m not sure what the moral of the story is, but it surely raises a question for me: is Blogger easily hackable? If whoever hacked it would have guessed/sniffed my password somehow, they would also have access to my Gmail account, which would be quite a bit more worrying, but that doesn’t seem to be the case. Of course, I changed my Google account’s password after this.

I do remember one time when logging into Blogger with my account, I actually gained access to someone else’s blog, who was probably coming from the same IP address as I. Might they be doing any security checks based on IP? At that time I did nothing about it, but in hindsight I probably should have notified Blogger about that incident.

In any case, I’m moving my blog to villane.wordpress.com for the moment, also considering moving it to my own server later.
