I'd like to note that this bug was introduced along with the votesystem
when it was first used in l4d(2), where it was eventually fixed (whether
or not it was before the system was ported over and extended to tf2, idk).

I’m not sure why the vote kick doesn’t just save the steam id when the
vote is started.
Then it doesn’t matter if they leave beforehand, in fact, if they
leave prior to the vote finishing, cancel the vote and default ban
them for 12 hours.

The actual bug is a race condition. A votekick is a kick (a forced
disconnect, basically, by player ID), and a ban (prevents joining, by
SteamID).
If a player should disconnect while a vote is in progress, the kick
won't go through (their player ID will change as they reconnect), but
the ban will (since their SteamID never changes.) However, bans are
checked early in the connection process. So, if the player reconnects
before the vote passes, the ban won't prevent them from joining
(because it's not applied yet when they join!), and they bypassed the
kick because their player ID is different.
The solution to this is to check all connected players' SteamIDs when
a ban is added, and kick matching players. Probably not overly
difficult to do with SM. There are also loads of third-party votekick
and ban management systems, that aren't vulnerable to this.
One trick: If somebody should bypass a votekick, when they come back,
they're sort of in a state of limbo. If they should be kicked or
disconnect, they can't rejoin (because the ban is now in effect);
thus, kicking them a second time will get them off for good.

We recently started using Valve’s own votekick feature on few of our
TF2 servers. It seems you can prevent yourself from getting votekick
banned by disconnecting just before the vote goes through. Seen a lot
of players do this recently and it’s really an annoying problem.
Is there any way to prevent this or is there a SourceMod alternative
that prevents this?
