IJBM: Venmo forcing arbitrarion - how to opt-out of it
(This might not be applicable to you if you aren't in the US.)
I got an e-mail from Venmo saying that Venmo is updating their user agreement to force binding arbitration unless you opt-out in time:
Requires you to follow the Opt-Out Procedure to opt-out of the Agreement to Arbitrate by mailing us a written notice. If you are a new user, the opt-out notice must be postmarked no later than 30 days after the date you accept this user agreement for the first time. If you are a current Venmo user and previously accepted the User Agreement prior to the introduction of this Agreement to Arbitrate on May 23, 2022, the opt-out notice must be postmarked no later than June 22, 2022.
Here's the page with instructions on how to opt out: https://help.venmo.com/hc/en-us/articles/360062640153
