WorkStream was moderated

I urgently needed the services of translation of documents, I turned to a specialist and wrote him a message. After that I found the phrase "Uh-oh! Your WorkStream was moderated
Our Moderation Ninjas detected content in your WorkStream, which was in violation of our Terms & Conditions. For that reason, your message never reached Yauheni's Inbox. If you want to talk this through, just Contact us". I can’t understand what happened ??? thanks
