Glad to hear the change of heart here and the guts it took to write it up. I know that's not an easy thing to do, and it likely burned some bridges.
The point about it being gambling, and therefore, taking advantage of idiots, yeah that rings true. The mass proliferation of gambling and the true compulsive addiction and ruin of mostly young men, it's hard to look at oneself and state that they caused that pain for other and their loved ones.
The next step is, of course, to do the very hard part: use the money gained for good. The author mentions that they are a hypocrite for only speaking out after making their money. They need not be so. Finding legitimate ways to use the ill gotten gains for good is a bit of what they built their skills in, after all.
I hope to someday see the next post of theirs detailing how many people they helped and how many lives saved, families reunited and made sound again, based on how they used this new wealth for good.
They are very far from the end of their story, but the midpoint, so to speak, has been passed.
