A No Guarantee Disclaimer is a warning that you are not guaranteeing anything. It's especially useful when you're publishing content on the web and want to make it clear that you aren't responsible for what other people write.
A no guarantee disclaimer is a type of legal disclaimer that warns people that they are not being guaranteed anything by the person who published the material. A no guarantee disclaimer can be used anywhere, but it's most common in contexts where a company has published information on the Internet that it wants to protect from liability.
The purpose of a disclaimer is to inform website visitors that their use of the site is at their own risk. This is particularly true when the site contains user-generated content such as forums, blogs or comments sections. While these types of sites can be very useful for sharing information, they also create legal risks for businesses because they allow users to post potentially defamatory statements about others (or themselves).
Since there's no way to control what anyone else says online, disclaimers are one way of trying to limit your liability in this situation. They can also help protect your reputation if someone makes claims against you online that are false or misleading and give you an opportunity to refute them before they go viral.
