近一個月，網站開始冒出許多垃圾留言，跟當年決定換掉TrimothyHUmphrey’s CAPTCHA時的情境相仿，三不五時會冒出一堆看不懂的洋文廣告，很多甚至是俄文、法文，一目了然的只有 我今年15歲，我有5" 之類的威而剛廣告(應是不了解台灣鄉民的實力，才膽敢跑來班門弄斧貼這種廣告夏夕夏景):

使用WhatIsMyIpAddress的IP查詢服務，發現留言IP來自烏克蘭、俄羅斯、南韓... 等國家，其中不乏同一IP連續留言多篇，或隔幾天重複留言的狀況，依此研判，應是垃圾留言機器人無誤，原本固若金湯的reCAPTCHA，莫非已被機器人攻破?
reCAPTCHA似乎未提供停用語音測驗的選項，若上述推測正確，在Google工程師想出克服之道前，恐怕還得被垃圾留言騷擾一陣子...
有在使用reCAPTCHA的朋友，近期是否也開始出現來自國外的垃圾留言? (我的案例以英文文章居多，推測是文章被引用於英文網頁或討論區，引來攻擊) 若大家都有類似發現，reCAPTCHA被破解的可能性就更高了。
