Discord should be abandoned as it’s not in the fediverse and especially because it’s not open source. This platform should never be used a an official place for one’s own platform.

When you’re constantly getting attacked and having issues, sometimes you need to do stuff you don’t want to do, just to be able to get stuff done.

In a perfect world I think devs wouldn’t want to use Discord, but it’s one of the only options that won’t be constantly taking down with attacks.

What has Discord anything to do with any attacks, or preventing any of them?

If lemmy is being attacked, mods need a platform to coordinate.

Discord has DDOS protection through their hoster, which was the primary means of attacks on lemmy.

Did the Matrix servers get attacked?

I can’t answer that, but my rebuttal would be these are targeted attacks, I don’t doubt they wouldn’t attack matrix if lemmy was using it to coordinate.

Matrix is federated, supports private channels, encryption, and cryptographic user signatures. It’s basically un-attackable (unless you open a channel to everyone).
