Is the Ashley Madison website legal to use?

The Ashley Madison website is indeed legal to use in many jurisdictions around the world. It operates as an online dating service that is marketed towards people who are married or in a committed relationship, offering a platform for those seeking to have discreet extramarital affairs or other types of casual relationships. While its business model and services can be controversial and may clash with social or personal morals, the website itself does not violate laws by simply providing a venue for adults to meet; however, users should always ensure that they are in compliance with their local laws and regulations as there could be variations in the legality of such services between different regions or countries.
