Users appreciate the WordPress plugin's effective spam filtering capabilities, significantly reducing spam on Gravity Forms while allowing legitimate messages through. It’s praised for its simplicity, ease of installation, and functionality, often eliminating the need for CAPTCHAs and reducing the reliance on other plugins like Akismet. Users find it particularly valuable for managing client sites and high-traffic forms. However, some users report that it can be overly aggressive, occasionally flagging valid submissions as spam, leading to frustration. The performance can vary, with some experiencing high false-positive rates, particularly on forms with attachments. Despite these drawbacks, many still recommend it for its overall efficacy.
