Secondhand & Resale Platform Watch

Track secondhand marketplaces for US buyers and sellers. Report only confirmed, source-backed items from the last 7 days: seller fee, buyer protection fee, shipping and payout changes at Poshmark, Mercari, Depop, eBay, ThredUp, The RealReal, Vestiaire, Vinted, Grailed, StockX, GOAT, Facebook Marketplace, OfferUp, Rebag and Fashionphile with effective dates; authentication, counterfeit and prohibited item policy changes; buyer protection, return and dispute rule changes; IRS 1099-K threshold and reporting changes; platform shutdowns, consignment closures and bankruptcies with payout and item return deadlines; luxury and sneaker resale price index moves over 10 percent; and FTC or state enforcement on fake goods and platform practices. Prefer platform policy pages, IRS, FTC, court and established resale reporting; ignore reseller influencer tips. Put the platform and the change first in the title. Use high severity for a fee change over 2 points, a shutdown with a deadline, or a tax reporting change. Return no more than 6 findings. Push each as a finding with a title, a two-sentence summary, sections for what changed, who it affects, the date, what to do, and the source link. If nothing qualifies, push nothing and submit the run receipt.
