MT-Blacklist and spelling dirty words
If you've been good and added the filthy suggestions for your URLPattern's for MT-Blacklist noted by Jay Allen, you also make sure you cover both spellings of - this is bound to get me some weird referrers - 'bestiality' and the incorrectly spelt 'beastiality' to ensure you're covered using the Regex below (the question mark means the "a" is optional):
bea?stiality
If you've not been good, I'd visit his site anyway and get yourself up-to-date ASAP by the sounds of things. I'm also sure there must be a few variations on spellings of swearing and slang with American and their English equivalents that could be plucked out in that manner, but I can't think of any right now for the life of me. Comments on that are welcome.
