In my opinion you don't have any kind of mechanism to detect compulsive gaming (like having daily deposit limits), and in my opinion it is a mistake and an irresposability from your side, but of course cannot be discussed here as it seems that you are throwing me directly to the Casino general T&C tiger.
I'm going to address you to the Spanish Laws. Please note that as per your article, I am solely and separately responsible for complying with the Spanish Laws. Let me add another thing. You, as a merchant, seller, gambling site, and since you are offering the game in my Country frontiers, are TOTALLY subject to the Spanish Laws.
Let me retrieve the current Gambling Law in place in Spain (Ley 13/2011, de 27 de mayo, de regulación del juego), officially published here: http://www.boe.es/buscar/doc.php?id=BOE-A-2011-9280
Art 6: Objective and subjective prohibitions: 2. From a subjetive point of view, it is prohibited the participation in the games defined in this Law to: b) The people that voluntarely had solicited to be interdicted / blacklisted from gambling activities. 3. With the sole intention of granting the efectiveness of the above mentioned subjective prohibitions, the National Gambling Comission, will establish the relevant measures that, according to the natureness of the game and the potential prejudice to the participant, can be required to operators. Accordingly one "Interdiction List" and another "people vinvulated to gambling list" will be created. Both will be valid in the whole National territory.
I'm tired of translating Laws into English. You can read the whole document where you will find more circumstances that apply to this case and to your current status in Spain.
Basically I was registered in the correspondent Spanish Interdiction List list while playing in your casino as I supported you with the relevant document. A National Law has more force than one Casino general T&C. Remember that you are licensed by Curaçao but you have to accomplish with the Laws of the Countries where you render your gambling services (it is the same reason you have used against me addressing me to your T&C the one I'm using against your argumentation addressing you to my Country Laws), as you are rendering electronic services INSIDE the frontiers of the Country.
I have deeply discussed this fact with you with no success. Let's hope we can reach a friendly solution were you can demonstrate your compulsive gambling social responsibility.
Again, I'm not searching for any benefit here. I have a very good opinion of your Casino (as shown in the rating I posted) but it is not acceptable that you simply look to the other side when you have strong proofs of compulsive gaming in your website, moreover when you are breaking the Country customer Laws.
