I didn't meant to discuss how this should be done or not done, nor the merits of taking down this emulator's repo. I was mostly making a point that one can maliciously take down Gitlab projects and get the accounts of all the contributors blocked immediately without actual proof of wrongdoing. It's not a platform or company which can be trusted. Imagine you start a successful open source project or a company does that. A competitor or someone who wants to do harm can just instantly take down your project and get everyone banned immediately.
