It's not a coincidence you see the same name pop up, every time someone gets bullied out of the discord.
Have you ever dealt with someone that constantly lies and misrepresents your opinions to make you look like a villain? Have ever gotten frustrated, because the person you're arguing with is constantly shifting the goalpost to their benefit? Have you ever said something needlessly rude out of frustration? How would YOU react, if after dealing with all this disingenuous bs, YOU get told to watch your tone or you get banned for being toxic?
The justifications after a ban always make logical sense, true. But if you read through the logs with even a little bit of empathy, it becomes clear very quickly who the toxic person in those interactions is.
Edit: I'm not talking about a specific person getting banned. This happened numerous times, including newcomers.
I'm not even including the horrible software they've authored and cargo culted into the language's ecosystem and tooling. That should be enough of an offense to be removed from any decision-making role.
He didn't cargo cult his software into the ecosystem. He made the ecosystem. Nimble is the package manager because there was no package manager until dom wrote one. Jester is the default web framework because it was first, and despite its age it's still pretty good. Same for choosenim. And asyncdispatch. And all of the other tools/libraries that he wrote.
Obviously writing some early software doesn't give him a free pass. I could understand the attitude if he was a jerk, but I've never seen him be anything but helpful.
Try to advocate for replacing any of dom's tools / software packages and see what happens. Try to advocate for taking Nim in a direction counter to what dom perceives as the right one, even though they no longer contribute to the language anymore besides telling people to fix their broken software they're no longer willing to maintain, or to throw their weight around in RFCs / IRC.
This is the type of insecurity and paranoia one can expect to find when hanging out in Nim discord.
