Someone who has recently made valuable contributions to one of my projects has approved a pull request coming from someone else and added a (slightly weird and easy to misunderstand) comment. This might have made it seem like this was an official approval (and official weird comment) from one of the maintainers.
I like this person and don’t want to discourage him from contributing, but I as the sole maintainer and owner of the repo, want to be the only one who is able to approve a PR.
Is there a config setting for this that I have missed? Or does someone who has ever contributed to the repo gain approval privileges?
EDIT: I understand that this person doesn’t have write access and his approval does not count towards mergeability, as the help text says. Still, I find it very weird that basically, random people can approve PRs.
