Contact details in the chat
While there is no booking, the conversation does not carry contact details. A message containing a phone number, an email address or an external link is refused and is not sent.
The check runs on the server, on every message, from every client. There is no way around it through the app or through the browser, and there is no difference between the site and the app.
A refused message does not reach the other side at all. Write it again without that detail and send it.
The moment a booking closes on this listing, the check stops applying to that conversation. The address and the phone number open in it at that same moment anyway.
The rule exists so that arranging things stays inside Peelpel, where there is a record of what was said if something goes wrong.
