內容簡介
Captcha/Honeypot (CF7, Avada, Elementor, Comments, UltimateMember, WooCommerce) 可讓您輕鬆啟用自訂規則、驗證碼和基於 IP 的保護設置,以停止不需要的垃圾郵件。
您可以決定哪個驗證碼是最適合您的。可以使用蜜罐、算術或圖像驗證碼來保護您的表單。
您覺得這個外掛有幫助嗎? 請考慮給它一個五星評價。
驗證碼保護可以全局激活所有表格,也可以僅在特定表格中進行本地保護。
例如,可以進一步設置基於時間的保護,以定義訪問者在兩個時間段之間可以提交表格的頻率。這樣,您就可以輕鬆阻止機器人一再使用表格發送多個垃圾郵件。
同樣地,您也可以激活計時器,在特定時間內假裝表單提交。取決於表單,只有機器人才能在幾秒內提交這些。因此,您可以啟用此功能以利用此優勢來識別機器人並阻止它們發送垃圾郵件。
驗證碼插件易於使用,您可以從自定義界面中管理所有必要的設置。
