Right now there’s no way to cancel all devforum sessions. Whenever someone gets compromised temporarily, this means they can go on a rampage here until a staff member forcefully kicks them out.
It would be great if the “log out of all sessions” button can also send a signal to the Discourse software somehow to kill all sessions here.
Killing all logged in sessions on the devforum should also be part of procedure for the team at info@roblox.com when someone has been compromised.
