Whether or not you have a factual and legal basis for filing a lawsuit against the company that owns the website that has an offensive post about you is best determined after consulting with a personal injury attorneyMany businesses that own such websites take the position that they are simply transmitting information submitted by others as part of their first amendment right of freedom of speech. Such freedom of speech right is typically asserted as an affirmative defense to the type of lawsuit that you want to file.I suggest writing the business that depicts you a letter requesting that you be eliminated as soon as possible from it as a start before you consult with the suggested personal injury attorney.
