What is a cybersquatter?
A cybersquatter, or domain squatter, is someone who registers domain names that are trademarked with the intent to profit from the domain. Usually, the goal is either to profit from traffic that goes to the domain or by selling the domain to the trademark owner for an inflated price. This is against the United States federal Anticybersquatting Consumer Protection Act and if this happens to you, you should file a Uniform Domain Name Dispute Resolution (UDRP).
Many cybersquatters also typosquat, which means they register typos of trademarked domains, such as dinadot.com as opposed to dynadot.com.
Please note that a cybersquatter is not the same thing as a domain investor.
