Looks like PROTO was on for a while, turned it OFF about 15 minutes ago when I returned to the board.
FYI:
PROTO will come on automatically if site is under attack by multiple IPs, could be any board, not just this one.
Often there's someone around to turn it off. If not, it will eventually turn off if the attack breaks off. If ongoing or sporadic, will continue until turned off.
