First, analyze the amounts of data the website requires from you. If it only needs a bare minimum such as your email, you are good to go. If the site wants to know more, including your phone number, social media accounts, and exact address, this can be viewed as a red flag. The most reputable and safe hookup websites also treat your personal data seriously. They should promise that your data will never be collected or given to third parties without your consent. Also, look for SSL encryption and a variety of safe payment methods to make sure the website is secure enough.
