No misuse or abuse of permissions (e.g., randomly disconnecting, muting, or moving others in voice channels).
For staff, instead of resigning, request @Administrative Leave. You're not a slave and should prioritize your problems. This does not mean abusing administrative leave to avoid your duties.
It's your responsibility to take care of your account and identity. Best practices:
Do not click on random links.
Avoid downloading unnecessary software, especially free or suspicious ones.
Steer clear of software by individuals hostile towards COI or its principles.
