I was hoping someone would know why it was blocked as malware, thinking it might be compromised and that people should be warned. VT says it's safe though so it's likely a mistake. Not sure what you mean about traceability. You could check the github.
I don't think that would break it because you have a limited amount of time. You base it on 1/e of the number of people you expect to date not the number of potential options.
The issue isn’t as much as bans but that the online multiplayer service won’t let you log in or that servers will auto kick anyone who fail the AC health check when they join.
