OfferUp

As quoted in a prior review (not re-verified this pass; OfferUp's terms page blocked automated retrieval), OfferUp's arbitration clause applies RETROACTIVELY — the company can update its arbitration terms and apply them to a dispute that already existed BEFORE you ever agreed to the new version, 'whether or not' you'd already started a dispute. Most companies' arbitration clauses only apply going forward from when you agree to them; this one can reach backward.

Arbitration

Binding arbitration explicitly applies RETROACTIVELY — the Terms state that amended arbitration provisions (including 'consolidation of disputes' rules) apply to ANY dispute arising before a customer even agreed to the amended terms, 'whether or not notice of such dispute was provided, or arbitration was initiated, prior to your agreement to the amended Terms.' This retroactive-application language is more aggressive than most other arbitration clauses in this tracker, which typically apply going forward from acceptance rather than reaching back to cover disputes that arose under a PRIOR version of the terms. Also explicitly bars 'class action refund claims brought by a class of taxpayers... related to taxes collected and remitted' — an unusually specific carve-out suggesting past tax-related disputes with customers.
