>What would trip that off?

It has only happened to me once some years ago and that was with an experiment with developing body filler automatically from a library of sentences (in my "elegant spam" experimentation days). Unfortunately the person doing it decided to use an auto-translation tool to translate a page into French and back to English to create a new page. The resulting text made no grammatical sense and tripped a filter immediately - just for that page. Nothing we did could restore the page.

I've also got a situation currently where an auto-filter has been tripped immediately on a new site through (I think) the algo determining that I have hidden links on a site where I don't - confusion between layers/tables and bgcolor. I've reported this myself to spamcrusader.
