I just sent a new community team message using the moderator action "Contact community team" from a user profile. After that, I received an email from Stack Overflow Technical Support to my private email address:
An issue has been created on your behalf in our support portal. You should see a response from us soon with more details or an answer to your question.
The Stack Overflow Support Team
This part is followed by the full details of the community team message.
This should not happen, and this had never happened when I had sent a community team message before.
