It has happened before https://annaclemens.io/discord

Yes, I remember when this happened. Everyone who got banned had their accounts unbanned (I was not banned however, and I've used Ripcord daily since 2018). You were also just as likely to have gotten banned if you used an outdated Android client.

If they're willing to lie about using a third party client (which is what they did to initially reach front page here many moons ago), I'd wager they were actually attempting to automate their actions instead of "BANNED after manually pressing 6 buttons".

What prevents Discord from doing a synchronized change of their web client and server APIs and using accesses to the old API to detect Ripcord users, then banning them?

Nothing, but in doing so, they'll likely ban non-Ripcord uses who are using outdated clients as well, followed by a bunch of support tickets by confused users.

Nothing whatsoever.

Yeah, this is what I use, and I've not been banned or anything.

I have been locked out of my account, though. There was a week during which I got locked out, and had to re-authenticate with 2FA to get into my account, once a day. However, they eventually stopped doing that after enough support tickets rolled in, and Ripcord has been rippin' along ever since.

I'm using Ripcord for over 3 years now and love it.
