Then the way you have explained it doesn't make sense. The way I see it
is the server uses client time for when to end the ubercharge. Client
time can be stopped by client stopping sending commands to the server.
But the server should have never trusted the client with this. There
should be a server timer counting the ubercharge length - in case the
client cheats or crashes or simply loses internet connection to the server.

From the description it looks like this bug is purely server side
and could for example happen if client lost internet connection
during ubercharge - introducing VAC here is only going to hinder
finding and fixing server bugs and possibly ban innocent users.

Things like these are why we need a new, revised VAC, which actually
poses a threat to cheaters now that TF2 is F2P.

BTW, Evan added me on Steam to discuss this. Not going to

He said that yes, the not sending usercmds part was right.
But, as
some of you would remember, Valve fixed a bug where Medics
could
infinitely uber themselves, but infinitely ubering someone
else wasn't
fixed. Currently, the client handles the timing of
ubercharges. They
end when powerplaytime < clientticktime. clientticktime is only
updated when the client sends a usercmd. No usercmds being
sent means
infinite ubercharges.
Packet manipulation could be used, among other methods
which I won't
reveal.
