So what happens if an individual or business launches their website, with ideal domain name, trademarked word, SEO etc. etc. and suddenly there pops up a number of bad reviews across multiple internet forums such as yahoo answers, warrior forum, blogs etc.
Maybe the reviews were from someone who hates the guys who run the site, (which is most likely for that to happen at once) but how does the new business retaliate:
Create accounts on all those forums and reply in defense.
Ask the forum owners e.g. warrior forum, yahoo etc. to delete the content.
Create fake positive reviews on blogs or forums.
What can be really done in that case. I know it's unrealistic, but it only takes one moron to do it to you if he wishes provided he knows the business.
