An interesting question that I've flip-flopped on a few times.

I'm not a fan of The List and never signed up. I think that runs counter to what FT is about. At the same time I've read a few comments - one in this thread and others in different threads - from folks saying they tip the airlines off to loopholes and then get a reward from the airlines. This really strikes me as unscrupulous if that loophole was discovered through FlyerTalk. It saddens me to think there might be people on the board who are using it to benefit themselves at the expense of the FT community, which by nature has been very giving.

Personally, there are some things that have been posted that I haven't taken advantage of because they strike me as wrong ... but that's one of those ethical decisions best left to each individual to decide. There have no doubt been some I have taken advantage of that others would see as wrong.

One thing I'm definitely against is criticizing those who do post loopholes and errors. At the same time, I also have seen some of the same people who argue for full disclosure not disclose loopholes they find. That's wrong too.

One thing PremEx does sometimes, is post a good tip way down deep in a thread that appears unrelated. I've picked up some good info that way and it doesn't easily tip off company lurkers.

In sum, if some people want to keep their tips to themslves, so be it, but please don't criticize others for trying to be helpful participants in a community that was built around sharing.
