I thought the GrapheneOS community would be interested in this, because many discussions are happening on Discord.
Discord's new terms of service dated April 15, 2024 now have sections requiring mandatory arbitration, unless you email written confirmation to opt out by May 15, 2024 (within 30 days of the new terms of service).
Opt-out. You can decline this agreement to arbitrate by emailing an opt-out notice to arbitration-opt-out@discord.com within 30 days of April 15, 2024 or when you first register your Discord account, whichever is later; otherwise, you shall be bound to arbitrate disputes in accordance with the terms of these paragraphs. If you opt out of these arbitration provisions, Discord also will not be bound by them.
