Cause of death: the autopsy

The pre-set probe needed 2 of 3 leading crosslisters to have at least 20% one-star reviews. Only Vendoo did (23%); Crosslist had 3% across 1,095 reviews. Delisting complaints were a minority (3 of 29), many 2026 entrants already compete, and the guard would need logged-in scraping of Poshmark and Mercari.

The numbers

None. It was never built, so there are no visitors, sales or ad spend to count. It died on paper, which is the cheapest place to die.

Could rise again if

The report left no way back.
