This post is not to recover my coins, (although I would like that), but to see the possibility that the sites begin to block not only the accounts, but also the IPs from which those accounts were connected.
Greetings to everybody and thanks
Before I begin, I would like to express my deepest regrets from your very unfortunate situation. While I do understand the conflict and difficulty of addressing your addiction, what you did is the first step towards your recovery. Since you already did the first step, which is to acknowledge and do something about your addiction, relapses are nothing but normal situations for a person undergoing such recovery.
With regard your issue, unfortunately, I doubt that gambling websites would do such a move. While there may be gambling websites that advocate in battling against addiction, they would never create a system where they would IP block a certain ISP as this would cost them tons of money. Again remember that these are businesses which aim to earn as much profit as possible.
