Captcha Some Dirty Words, Why Don't Cha?

A distorted image of letters and numbers used to prevent automated use of websites; Anything that a human must do to prove that they are not a computer

Every time I post a link to my blog on Facebook, I have to complete a Captcha request. Usually the words are very innocuous, like the words above, "contribute" and "of".

Yesterday's words: "cumstance" "asside"
Today's words: "get" "perverts"

Am I the only one being sexually harassed by Captcha?
