I’m calling Bullshit on this one guys.
I’ve been a member at FortuneJack for over 5 years now. Have been a VIP for much of that period. I have never received nor heard of this $100 no deposit bonus. I have received some small no deposit bonuses over the years. I was lucky to cash out a few of them of them.
On every instance there was always strict wagering requirements which were exhausting to complete. On top of that the cashout limits on these bonuses is always very low. On a few instances I would win $1-$2K and they always would revert back to the same 0.015 BTC maximum win from a no deposit. Always. Not once have they lifted this cap or allowed me to withdrawal funds in excess of this.
To be certain, I just reviewed the most up app o date version of the bonus terms to ensure that this policy was still in place as it has been for years now! Navigating to the ‘bonus terms’ page which is linked in the footer. I found that the policy is exactly as I recall it. I will post an image of that policy to highlight this .

FortuneJack is a stickler for rules and conditions like this. They are completely inflexible and rarely give the player any special consideration. Even when they are obviously in the wrong. They have never been very empathetic to causes such as this.
With that said, I can say with a fairly high degree of certainty, that the OP is not being truthful about his account of the situation. I don’t believe he even received a $100 no deposit bonus to begin with. But even if he had - 0.22BTC - this Policy being in place means fortune Jack would not have to pay hom .22. They could revert that back to 0.015. Like I said, I know them well enough to know that they would never ever ever pay out this amount on a no deposit bonus or a free spin.
Why this guy would fabricate this story is not a question I can answer. There’s a few possibilities that I could speculate as to possible motives but I will leave that for everyone else to determine.
Is this a next level expose that I'm reading? haha I can confirm that as a member of FortuneJack, I've never received such promo, or any promo close to that amount, that didn't even require deposit.
OP's win is possibly real though.
