 Instances of abusive, harassing, or otherwise unacceptable behavior should be reported in the Matrix room. If you violate this code of conduct, you will be banned, *even if you otherwise make decent contributions to the project*
 
+## Why Have a Code of Conduct?
+
+Unfortunately, as you may already be aware, the game hacking and the wider gaming community is [filled](https://kotaku.com/call-of-duty-has-banned-over-350-000-players-for-racism-1846975082) [with](https://www.unknowncheats.me/forum/images/smilies/black.png) [bigots](https://en.wikipedia.org/wiki/Gamergate_%28harassment_campaign%29), and otherwise [unsavory people](https://en.wikipedia.org/wiki//pol/) who tend to drive away contributors and slow down development by engaging in pointless drivel. To this end, having a code of conduct ensures these people are quickly removed before they could cause significant disruption to the project. This is purely basic decency and has nothing to with being "woke" or "liberal" or whatever certain people may interpret it to be. If you feel that not being able to say racial slurs, for example, is a significant violation of your rights, then please feel free to contribute elsewhere; you're in good company, after all
