in my opinion it is true that sometimes airlines will loose (and the costumers, for a limited time at least) winn, if many (too many?) costumers profit from 'extreme' offers/loopholes/whatever.

Sharing/posting openly this posibilities might just help the airline to get to know early/earlier (and I agree, may be in the long run limit and/or define new rules for frequent traveller 'perks') - which, if the philosophy is not to 'hurt/hit' airlines (and their frequent flier programs) 'under the belt', would/should be even more ok/accepted then.
