Thankfully we haven't had any big problems in the CodePen community. Y'all are a very supportive and helpful community! We want to make sure it stays that way and we want everyone to know where we stand and what to expect.
To that end, we've posted a public Code of Conduct page. It essentially covers what we would consider to be unacceptable behavior and what would happen in those cases.
This is in additional to our Terms of Service which covers the legal side of things.
