Since when you people become so moralistic?
Poor man from Slovakia asks the age-old question about reward programs (which is new for him) and a bunch of capitalists from the land of Liberty, from his Big European brother and even from Down Under kicks a **** out of him.
In reality I will tell you what everyone is doing: don't violate rules, bend them to your advantage. Do you have parents, children, relatives, friends who do not care to use Clickrewards and to be registered at some particular airline? Ditto! Think for youself.

Small tech advise: download Netscape 6.1, it has a nice cookie manager (under Privacy and Security). It allows you to watch your cookies, keep useful ones, reset ones which need to be reset.

I see some heavy-hitters on this thread and I'm really surprised: by these days of dotcom doom you should realize that no amount of your compassion will save unsustanable business model. If they have holes, they should patch them, your obstinence will not help a bit, they will learn how to make money or will fail regardless.

Cheers.
