I'm a bit concerned by one of the candidates running for the Organisation for Transformative Works (they run AO3 and Fanlore) board elections this month.
This person also keeps bringing up VPN as a way to stop the hacking incident from earlier this year, alongside MFA.
MFA could have potentially helped, but unless someone was waiting to perform a man in the middle attack at some cafe an admin was at... VPN wouldn't have helped.
