Everyone who is saying take responsibility and stop gambling doesn't understand the addiction part. Even if you happen to gamble yourself.
He did take responsibility. He asked for the ban. The addiction is what brought him back. Yes, he could have just made another account. That doesn't mean that stake didn't do wrong by him. They say they practice responsible gaming and should have stood by it. His name should have remained in place.

Op I'm sorry this happened to you. I have a pretty bad habit myself. I can. Admit I have a problem but I can't bring myself to even take this first step of self exclusion yet. Each day it seems to be getting closer and closer though. I hope you find the help you need and I find it as well.
