I'm a little confused - did you mean the linked blog post has stock photos and looks like a PR nightmare?
If so, maybe I'm just a little biased here but the blog/website looks pretty nice, IMO :). Is it really that bad?
If you meant that allowing anyone to publish posts or add files to your blog/file store could be a risk, you can choose to allow only specific emails that you trust to post blogs/add files. Hope that clears it up. You can also hide posts after submission and files in your File Store are by default private - these are your safety nets.
