Someone wants to know about the type of insurance that would cover you if you slander someone on the internet.
Let’s start with the basics: slander is saying something falsehood about someone that causes them injury to their reputation. So, if you write that Joe Smith is a thief and liar, Joe may be able to sue you for damages.
So, what type of insurance do you need? If you run a website for profit, you probably need business insurance. Most business insurance policies cover you for slander under advertising injury or personal injury. (Check your specific policy.) If you make a comment on a site like Craigslist, then your homeowners insurance may cover you under your liability coverages.
Keep in mind that each insurance policy is different. You should always read your policy to see what is covered.
