I know. But since you mentioned that you had never heard about the repo before, I wanted to fill in with a bit more information.
I know they are a bunch of hardworking people, doing a great job and the repo is trusted by many users and if I am not wrong is enabled by default in Garuda Linux.
However, the fact remains that whenever you add a third party repository to your pacman, you have to trust the source of that repo. The responsibility is only yours.
