Has My Blogger Account Be Hacked?

About a year ago, I sat down with the good folks at the BNI Westport Chapter and pitched an idea. I'd create a blog for them, enter their names, and they would provide the content, generating SEO for their businesses. BNI is a group of local networking groups where non-competitive members trade leads to help each other. Thus a lawyer gives a real estate referral to a cabinet maker, who gives a laptop referral to a computer store, and so on.

It worked. For most of their names, the first or second Google search took them to the site, established them as a BNI member, and provided contact details. BNI blog was also the highest ranked in the country - no small feat considering how many BNI chapters there are and they all have web presences

After two months, I cut the project off, but left the site up. It's been sitting on my blogger dashboard since August 2006, and out of curiousity I looked at it today.

If the image is not up, here is a screen shot. It looks like someone hacked into my account and put up pharmaceutical links, and even changed the title.

We use Blogger occasionally because the HTML Template is simpler to code than Typepad, and it allows you to map to a path, instead of a subdomain, but this is worrisome. Is it possible my Google account was hacked, and if so, how can I protect myself in the future? Can we afford to use Blogger as one of our platforms?

I've deleted the account, but of course could not do that if it were a client site. Anyone have any thoughts?
