Well first and foremost, I certainly would hope that no one would feel castigated here. If so, maybe we are all taking ourselves just a little too seriously.
Historically speaking, the past practices of FT were that if there was something good and by the book, then post away. After all, the point of the bonuses and such are marketing. The more people know about it, well, that's win/win. I'd put things like the Hilton profile update bonus in this category.
If something is either borderline ethically or if the tecchnique might be revoked/rule changed if too many people heard about it then the practice was to save those tips for FT get-togethers. It was an incentive to come to the gathering and a sport of one-ups-person-ship at the gathering. I tend to put ticket nesting, back-to-back deals and bait and switch into this category.
If something was clearly over the line ethically or just not fair cricket, then the practice was to either talk at length about it or bash whoever had the audacity to suggest actually doing it. Like selling upgrades and miles on ebay.
Anyway, not to say that anyone is (or ever was) under any obligation to abide by any of this, just that this is my impression of how it used to work on FT.
How it works in the future, well, that's up to each of us individually...
