        comment: "To combat excessive pull requests, the go-ethereum team now requires contributors to [register](https://pad.ethereum.org/form/#/3/form/view/8cfd7dbf415489a41cfefb7f4901d549/) as a collaborator. Please see the [policy](https://github.com/lightclient/geth-collaborators) for more information. Thank you for understanding, we look forward to reviewing your contribution!"
