Actually, I pasted your message 20 times into a test message to test the new
rule and it didn't match the new PORN_3 at all.

This leads me to notice another difference between the old one and the new
one: the old one checked for 3 occurrences of any word on the list, while
the new one checks for matches on at least 3 words on the list.

In other words, "wild asian hot peppers" would match the new PORN_3 because
it includes three separate listed words, but "wild wild wild hot hot hot"
wouldn't match because it only includes two of the words on the list. Same
with your example.

This is not necessarily a bad thing but the threshold should definitely be
something larger than 3.
