The fee charged by OKex seemed to be strictly equal or higher than the cost to route the payment. There is no way one could make a net profit from OKex using this attack.
This seems to be a viable solution, as noted in the post. So if services offering LN withdrawals adhere to this, then they’re fine
Relieved to hear that this isn't much of an issue anymore. However, the reason I became aware is because our friend Pseudo Zach over Sats4likes has been getting victimized by this recently in numerous attacks.
