Negative blogs can really be an issue, as more often than not they are managed by people who remaining anonymous , but times are a-changing, with more people and companies being taken to court to reveal the anonymous blogger. Another anonymous blog decision.
Until such time that it is common law for everyone to post a blog and information be recorded about them then the other alternatives are:
Hi have put the two main blog platforms with advice and guide lines on how and why they may remove a blog.
Blogger takes violations of our Terms of Service very seriously. We encourage you to read through our Terms of Service as well as the Blogger Content Policy before filing a report with us.
After careful review, Blogger may remove content or place a content warning page before viewing content deemed offensive, harmful, or dangerous, such as:
Additionally, we are aware that there may be content on Blogger that is personal in nature or feels invasive. Please note that Blogger is a provider of content creation tools, not a mediator of that content. We allow our users to create blogs, but we don't make any claims about the content of these pages. We strongly believe in freedom of expression, even if a blog contains unappealing or distasteful content or presents unpopular viewpoints. We realize this may be frustrating, and we regret any inconvenience this may cause you. In cases where contact information for the author is listed on the page, we recommend that you work directly with this person to have the content in question removed or changed.
Here are some examples of content we will not remove unless provided with a court order:
In addition to spam and copyright issues, we will suspend blogs or blog posts for the following types of abuse:
If you find such content on WordPress.com please report it to firstname.lastname@example.org. Please provide specific links and/or quotations of the offending material or your complaint will be ignored. If the blog is written in a language other than English, make sure you provide a translation.
We will not suspend blogs for other reasons you might find objectionable. For example, we don’t suspend blogs for expressing negative personal opinions such as calling someone an idiot or crackpot (because those are opinions that can’t be proven right or wrong), for describing a negative experience they have had with a business, or for being offensive (see this section on freedom of speech for more information). Instead of asking us to suspend such a blog, please consider either responding in the blog’s comments or on your own blog/site to set the record straight, or simply ignoring the issue (blogs that use insults and bad language tend to have low credibility and low traffic in the first place).
The other ways to tackle a blog is to sign up to the same blogging provider and produce a much better, content rich and informative version, this is more likely to outrank the negative one in the search engine results page (SERPs).
Also your should look to bury the blog much further down the SERPs, we can help do this and protect your reputation from it happening again.
