I assume those people are simply foolish who says alexa is useless. Have you ever heared of a survey conducted by some institute on a "sample" of people and they assume that its true for remaining sample of peoples too, upto some accuracy.
Its the same thing guys.
Everyone of you trust alexa someway, but dont stop saying that its useless. Will you buy a website reporting 5k uniques a day and 5,000,000 alexa rank?
I know its easy to cheat alexa but it doesnt mean you simply declare them useless.

I think its simillar to: Google isn't useful at all...unless you are trying to search something.
Alexa is not fool-proof but I think it's a valuable tool to gauge your own SEO efforts. Relying on Alexa rankings to buy advertising on another site is more risky because the rankings can be easily manipulated. From my own experience with the Alexa toolbar, you can achieve a 400,000 rank on Alexa simply by surfing your own site with the toolbar activated. There are more sophisticated methods to achieve much lower rankings.
