Some countries have separate poker clients or separate poker sites only for players from that country. Usually in such cases, players from other countries are not allowed to enter.

What do you think in connection with this? Is this due to the excessive emotionality of the players of those countries in which poker reservations are created or something else? Or is it only financial security for the money of citizens of such countries not to flow to other countries?

This is mainly due to the varying legal restrictions on online poker among various countries.

For example, USA players have not had access to the main international Pokerstars player pool since Black Friday and PS has had to pull out of Australia more recently. PS can be played for real money in New Jersey but the player pool is limited to people within New Jersey only.

I think it is due to ignorance. From what I have read I can say that it is the case of Spain, they can only play with players from their country, France and Portugal. The reason is unknown, because even in these countries players must pay taxes

It's all about the legislation of that country and the taxes they charge.

As previously stated, mostly due to different legislation in different places.

Localised servers also might be a lesser factor.

This is related to the fact that poker has different agents in different parts of the world. Each agent will govern its own surrounding countries. This is also because each country has different legal restrictions on online poker.

Thanks for clarifying friends! Now I am convinced of the guesswork on this subject. Thank you for taking the time to discuss!

In different countries, different laws, respectively, different licenses for gambling and poker rooms, in order to expand the playing field, make different concessions.

just regulations. i know a story of a spanish player that move to another country to avoid the strict laws referring taxes to poker players.

Good morning everyone.
I believe that it has to do with the collection of taxes, pokerstars-eu, cannot operate in Spain, France and Portugal, because of that they made pokerstars-es, which has an agreement to pay taxes for these 3 countries.
If you go to the pokerstars lobby and look for Mtts of more than $ 500 in entry and that will start the next day, you will notice that there are a large number of players from Greece, in some cases all are from Greece, that poker players from that country have to pay tax on what you earned at the end of the day, if you have $ 1,000 in your account at the end of the day, you have to pay tax of that amount, what they do is register in Mtts that will start in 1 or 2 days and at the end of the day the account is out of balance and you don't need to pay anything, on Mtt's day just go to Mtt's lobby and cancel the registration.
