No need to response, but stake can just take action as the feedback development.

It's exchange system-based (tipping). If Stake seeing these as good feedback and see how big is the volume transaction, just like other casino do they just can easily make a system and development on their casino for the exchange service with (3-5% as usuall on every casino).

Then, these service will be died or shutdown by them self without (Stake) response to their service. Simple as that.
