In this talk, we will briefly introduce Hactoberfest, though not much introduction is needed as it is a well-known event. We will go through some fun facts and the history of Hacktoberfest fest and how it goes from 700 participants to more than 100,000. Then, we will go from why it is good for the open source community and from both the perspective of the contributors and the maintainers.

Then, we will have a switch of tones and looks at the fact that what happened in recent years that problems starts to appear. There are massive numbers of contributions and some of them is not meeting the need of the projects. To put it simply, there are a large number of "low-quality PRs" - e.g. meaning less fixing of wordings, formatting etc. Then we are going to explore various solutions, those that the organisers used in the past and the ones that I would like to suggest.

This talk is for anyone that cares about open-source contributions and would like to have a healthier community.
