@saramg I had a similar experience, although with even less reasoning, where someone started opening PRs to my repos to set up Travis CI. Nothing against Travis, but they were already using a different CI and nobody asked for it. I appreciate the contributions, but I couldn't get a good reason from them, so they were all declined. Out of curiosity I looked at their contributions and that basically was what they did across all the public repositories they touched.
