I favour the idea of publishing any idea on flyertalk.com. The more people read and contribute, the better the outcome. I don't mind if airlines/hotels/cars/... will close some loopholes afterwards (and it is still the question if it is cheaper for them to have a loophole that is used by a minority or spend a lot of money to fix the systems (and produce another error). It all depends from the current situation of how much money they loose). IMO, most airlines/hotels/cars/... know many their own loopholes (and surely much more about which we have no clue).

I profited so much from this board. I will contribute in future, too, and hope to give "something back" from that others will be able to profit. (And I think that the openess on the board also lead to wonderful meetings where people can exchange loopholes, too).
