This is completely non-E related, but I figured someone might know.
I just sent an email to one of my Congressional Representatives. I used the word 'dropping' in one paragraph, and it apparently triggered something in their web-form. I got a message saying that 'We have detected the word 'drop' in this field. This word is not allowed in our webform, per Congressional regulations. We have chosen alternate words to use in your submission; please review the changes in the form before you submit it.' (Actually, they replaced it with dr_op, for no apparent reason.)
I replaced it with 'falling' but that seemed like such a weird word to balk at. Anyone have a plausible explanation?
