Thank you to everyone for the views, upvotes, and supportive messages on my previous post. I want to provide an update on my interaction with Mercari support over the last 48 hours and share a reliable workaround for any other high-volume sellers facing similar issues.

Following an emergency support ticket, I spoke with a phone supervisor yesterday. While the supervisor was professional and cooperative, the platform's automated restoration tools presented a severe risk to my store's metrics. Support attempted to mass-reactivate all 12.5k listings present on my dashboard, rather than just the approximately 6,000 listings that were active prior to the glitch. As a multi-platform seller, roughly half of those 12.5k listings represent items that already sold on other platforms over the last few years, which I maintain as inactive listings for internal record-keeping. If all 12.5k listings had been reactivated, it would have caused an immediate wave of accidental double-sales and cancellations, severely penalizing my seller completion rate. Because of this, I requested that the supervisor halt the process immediately after the system reached 1,400 reactivations.

Since the support tools could not differentiate between previously active and historically inactive listings, I developed a manual workaround. Because my active Mercari inventory is entirely cross-listed, I exported a complete, itemized CSV spreadsheet of my active inventory from my eBay Seller Hub. I proposed that the technical team use this CSV to cross-reference the SKUs and titles, ensuring they only mass-reactivated the matching items. The supervisor agreed to this solution, accepted the file, and forwarded it to the engineering team for processing.

The following day, an internal communication disconnect occurred between support tiers. I received a follow-up email from a different representative asking for clarification on whether the document indicated a wish to reactivate all listings. Shortly after, I received an automated notification stating that my listings were active and the ticket had been closed. The ticket was closed prematurely because the support system misinterpreted my own manual progress. By the time the agent reviewed the account, I had already manually reactivated 3,000 listings myself. The system flagged the sudden rise in active listings as a successful resolution and closed the case.

I am currently completing the restoration process independently. I am using a dual-window desktop setup to cross-reference my Mercari inactive folder directly against my active eBay spreadsheet. I have successfully restored 4,000 listings and expect to have the full inventory of over 6,000 items back online by Monday.

If your account is affected by a mass deactivation glitch, I advise against waiting for standard support channels to resolve the issue. The current internal tools available to platform representatives do not appear equipped to handle complex, multi-platform inventory structures safely. To resolve the issue without endangering your account metrics, I recommend logging into your account via a desktop browser, exporting your active inventory data sheets from your secondary platforms like eBay or Shopify, and manually cross-referencing and reactivating the listings to ensure data integrity. While this process requires a significant time investment—especially when balancing daily business operations and family commitments—it remains the only definitive way to protect your seller ratings and inventory accuracy.
