All reviewers must abide by the code of conduct; they are also protected by the code of conduct. A reviewer should not tolerate poor behavior and is encouraged to report any behavior that violates the code of conduct.
The Charting Show team has a well-defined review process that must be followed by reviewers in all repositories under the Charting Show organization. This process is described in detail in the what happens after the report is filed section on the code of conduct page.
