He has been removed already. You can also self remove yourself in Settings if you desire to leave ShadowBot.

I do not desire to leave, I'm sticking with you shadowbot.

Glad to have you on board! Let us know what we can do to make things better as we are constantly working on this project! We just don't want anyone feeling like they are being "held hostage" by us!

How can I remove myself?

In Settings at the bottom there is the delete account form. We also recommend if you do leave to reset your password to ensure your private key is reset as well. This always best practice when you wish to leave any service that you provide a private key to.
