Well, that list is interesting.
I know of one particular keyword that is 100% valid, thus the reason for me looking at this thread - to if the list had some credibility. I would say
that there are many words that, by themselves, do not trigger a divert, however when combined with other keywords, they certainly would.
To see the bigger picture, think about grammar engines that word processors use and then take that technology and mulitply it by about 100 000 and you
can imagine what algorithms they use today
