I found a bug/exploit with !specme.
As you might know, you cannot change teams while your build-timer is running, to prevent quick-building exploit, where you go to spec and back, then respawn.
However, you can leave your team using !specme, and do the same trick. You can even bind "!specme; wait X; team [aliens|humans]; class [builder|ckit]" the catch in the bind is that X must be higher than your ping, but this is easily compensated for.
Wanna fix this exploit?
