Some bloggers also like to run a script or plugin that creates a captcha on their comment form.一些博客也想運行一個腳本或插件造成的Captcha對他們的評論形式。 A little doodle of letters and numbers that are supposed to be machine unreadable.有點塗鴉的字母和數字，是為了被機器無法讀取。 There are many different versions, including re-captcha which does a secondary academic job of classifying unidentified words from scanned documents when your commenters complet the captcha.有許多不同的版本，包括轉口的Captcha但這次要的學術工作，分類不明的話，從掃描文件時，您提意見complet的Captcha 。

Please don’t use captchas.請不要使用captchas 。

Captchas may help trap spam, although they don’t prevent human-bots from entering spam, because they can complete the captcha, but they are a pain in the behind. captchas可能有助於陷阱，垃圾郵件，雖然他們不妨礙人類的bot進入垃圾郵件，因為他們可以完成的Captcha ，但他們是疼痛，在後面。 There are two types of captcha that are particularly annoying.有兩種類型的Captcha是特別煩人的。 First, there are those captchas that open either in a popup window or separate tab after one has hit “submit”.第一，有一些captchas開放無論是在一個彈出窗口或單獨的標籤後，一，打擊了“提交” 。 This is just plain silly.這僅僅是平原愚蠢的。
