You can improve it or use a different system. IRC was just an example.
>May I ask why are you so against Discord?
It's like every goddamn website or service now wants to get as many people as possible and force them to make accounts on horrible terms. Discord spies on its users, tries its damnedest to identify them, makes you use a shitty client which is just a web browser, attacks third-party clients, lies about what a "server" is, and is overall just awful.
I don't have to make an account to use pregchan. Couchy doesn't get to know who I am. Tor is allowed. Meanwhile, Discord continually encroaches on imageboards and other forums trying to siphon away as many people as possible. If a group you want to participate in is only on Discord, your choices are let Discord fuck you or to abstain, and I don't like either choices.
This is only a basic explanation of why Discord is bad. I'll let someone else continue listing off reasons if anyone wants to.
