I've already had several idle discord accounts get disabled with no possible way to get them back. It's so annoying and I have not violated a ToS or rules of a server.
A serious discussion needs to be passed around in the developer communities to abandon discord outright due to these problems. There are still many other alternatives that just work. I literally think Discord culls free accounts because they want people to consoom more and sign up for "nitro"
They can get fucked.
