This made me laugh when I first heard it.

A few years ago a secretary working in the Reserves' Department at my local Wildlife Trust HQ, received an e-mail from one of the Trust's Reserve Managers which her e-mailer promptly blocked as spam on the grounds that it contained profane material.

Intrigued as to why a Reserve Manager should be sending such an e-mail, she retrieved it from her spam folder and opened it, only to find it contained nothing more objectionable than a list of the plants currently flowering on the Warden's Reserve. Puzzled by this she looked down the list and found the problem, the plants were listed using their scientific name followed by their English name in brackets and one of the plants listed was Thesium humifusum. (I suppose this could get blocked if I give its English name, so if you don't know, look it up, it's one of the toadflaxes).

we had a similar problem with a list of wanted animal carcasses. I actually got an e-mail from IT saying that I had triggered the anti-profanity filter. I will check at work what the 2 animals were.

I have just found out what it means in English
