Discord just announced a change to their Terms of Service, which restarts the clock on when you can opt out of binding arbitration. All you gotta do is read the "Opt-out" paragraph of Section 16 & send an email to arbitration-opt-out@discord.com from the email address you use to log in which states something as simple as this:
I am confirming that as of the date of this email, I am choosing to opt out of binding arbitration to settle disputes with Discord.
Boosts pls.
