While I didn't do the LatinPass, I do remember the ClickRewards + World Wildlife Fund promo where you could get 120 miles/$$ spent. CR really regretted that promo, as FT'ers jumped in for many tens of thousands of dollars.

And on a more regular basis, people share bonus mile promo codes, the recent special sales on discount J fares by AA/DL, etc...

I think that's what made FT such a valuable resource for so many. Even the hint that there is a "private list" where even better information exists would poison the community by creating an "us vs. them" mentality.
