The plugin works by using logic to identify spam comment submissions. No user interaction is required. The spam blocking mechanisms work transparently behind the scenes. Most human readers will require longer than a few seconds to read a post and comment so any comments submitted within a low time threshold are identified as spam. Comments containing a large number of links are flagged as spam. The plugin also uses an encrypted code to prevent recorded robotic submissions made across multiple sites as well as a honeypot. All field names are randomized to prevent detection based on a form signature.
