Your link to the Guardian article on spam blockers not allowing the word "erection" through caused me to laugh. My parish is the Church of St. Mary the Virgin, in Manhattan. Our Web address used to be stmvirgin.org, but because we used the word "virgin," many spam blockers would not allow our messages to go through. So we have changed to stmvnyc.org, and now we have no problems.  Apparently Our Lady through her intercessions was not able to fix this problem related to the word "Virgin," even though we were referring to her!

Call it the web’s immaculate misconception.
