But you didn't state any facts at all, only assumptions.
I'm sorry, but I don't feel like looking up the exact laws for EVERY country that SE sells product in and posting them all. The few rules that I did post up are indeed real and do exist in many countries, so they are not assumptions but are laws that exist in many countries. The legal challenge to detrimental entry fee is indeed real, and easily arguable in a court of law, so that too is a fact.

You asking me to post "facts" is actually a near impossible request as the only way I can post something that would satisfy your definition of "facts" in this case is to research every gambling laws in existance and either post or link them here. Instead, I posted a general guideline and a few restrictive laws that do exist, to illustrates the barrier that is common to most organization holding international contests.

If you believe that your country is wrongfully excluded, feel free to look up your own gambling laws and provide an action plan to SE as to how they can implement the contest in your country while still abiding by the governing regulations. (See what I did there? I responded to your near impossible request for "facts" with my own near impossible request.)

P.S. I will no longer be responding to posts here as I feel my presentation is concise and easily understood, and those who choose not to understand them are simply being willfully ignorant.
