We've just rolled out an automatic process for managing unresponsive seller accounts. This is only applicable to the bottom 2% of our 2,000 sellers, who are not responding to a majority of their inquiries. (This is also in addition to the reminder emails which go out for inquiries several days after no response.)

• After becoming unresponsive, the seller will get a private warning notice on their inventory page. This should be highly visible to them and is useful in case they are not seeing our emails for some reason.
• After one week, they will be sent an email notice.
• After two weeks, the ads will be automatically expired.
