 It is still worth bringing up if a core repo maintainer has a history of bigotry such as racism, transphobia, etc, if it's in the context of adding an alternative software or something to that nature, but still just be objective, e.g. "We should not add a link to x because it is maintained by a transphobic person, see evidence here" and just leave it at that. We'll take that feedback and reject a pull request or ask someone to modify it if it's relevant for community safety (like ensuring people avoid software maintained by discriminatory people for instance).
 
+If you must link or provide screenshots of something that displays bigotry, gore, or anything sexual in nature, you *must* add a content warning. Content warnings must be specific to the subject matter. Below, we will give you an example on how to do so:
+
+```html
+<details>
+  <summary>Content warning: Homophobia</summary>
+  homophobic content goes here.
+</details>
+```
+
+That will display like this:
+
+<details>
+  <summary>Content warning: Homophobia</summary>
+  homophobic content goes here.
+</details>
+
+Failure to do so will first result in a one time warning and future offenses will be considered a strike.

 # On handling rude comments in this repo specifically
 
 If you see someone behaving in appropriately, do not feed their behavior. Tag an admin (@jessebot or @cloudymax) instead. They will handle it.
