This means Roblox can use content you create — including games, artwork, or other materials — commercially and globally, without paying you, unless you are in the Developer Exchange (DevEx) program.
Roblox users — including children — face significant restrictions on their legal rights, as U.S. users must resolve all disputes through binding individual arbitration and waive the right to participate in class action lawsuits. Purchased virtual items and Robux balances can be forfeited without refund if an account is suspended or terminated at Roblox's sole discretion. You can opt out of the arbitration agreement by following the opt-out procedure described in Section 11 of the Terms, typically within 30 days of accepting them.
