Unlike Twitter or Facebook, Parler requires users to “agree to defend and indemnify Parler, as well as any of its officers, directors, employees, and agents, from and against any and all claims, actions, damages, obligations, losses, liabilities, costs or debt, and expenses (including but not limited to all attorneys fees) arising from or relating to your access to and use of the Services.”
In order to use Parler, individuals must also forfeit their right to sue Parler in court or join a class-action claim and instead must settle disputes in arbitration, a secretive process that typically favors businesses over individuals bringing complaints. (Neither Twitter nor Facebook requires arbitration in their terms of service.)
