Any web form or input area such as comments are susceptible to spam entering a site. For example, spammers can automatically input data into a ‘contact’ web form. Deleting this spam content can be time-consuming. There are many ways to prevent spam, though none are foolproof. Common tools include Drupal’s “HoneyPot” module and adding “Captcha” to forms that require users to spell out letters or numbers.
