Hello I cant respond to messages

I sent someone a link asking if it was the same item they were selling. Now I've been flagged and cant respond to anyone by message. This isn't against the guidelines that I can see. How can I get my account back?

Sounds like the temporary r37kprmm error code, give it 24h

If it still has not resolved after that time contact support.

In the meantime you should still be able to message via PC
