Got a "Potential Usage Policy Violation (openai api)" email on an account that's barely even active

I barely used the openAI api over the last few months, and what little use it did get was almost strictly for coding. And yet, I just got a Usage Policy Violation email. My usage dashboard doesn’t show any suspicious activity, so it doesn’t seem likely to me that my API key was leaked.

Anyone else getting these policy violation warnings for seemingly no reason?
