How to detect if a player logs out of the game in Minecraft?
I am building a Minecraft survival games map, in which the battle area is on a floating island. My friends discovered that if they are falling to the ground, they can quickly logout and log back in to escape fall damage and not die, thus cheating.
Is there anyway to detect if a player logs out so I can increment their Death score?
I'm building it vanilla, I'm trying to make a whole map automated with just command blocks and redstone, this is the last thing I need to do now.

Here's the format for the Update Aquatic (1.13):
Adding Score
/scoreboard objectives add JustLeft minecraft.custom:minecraft.leave_game
Clock Command 1
/scoreboard players set @a[scores={JustLeft=1..}] Death 1
Clock Command 2
/scoreboard players set @a[scores={Death=1..}] JustLeft 0
Adding to SirBenet's answer, if at all a player is looking to reset the Deaths score for any reason, simply do this:
/scoreboard players set @a[scores={Death=1..}] Death 0
The command format changed dramatically after 1.12, and for the better it seems. Removing things like "/testfor" and "/testforblock" and replacing them with "execute if entity " or "execute if block X Y Z "
TIP: adding elipses (...) after the numeric value tells Minecraft to check all values at or above this one; in this example, the command is checking for anyone with score "Deaths" greater than or equal to 1.

How can you tell when a player leaves the game in Minecraft?
You should try to not use the scoreboard, and instead try joining the server and when a player quits the game, a yellow message will appear in the top left corner of the screen, saying [gamertag] has left the game.Minecraft 1.19: How To Detect If a Player Is Crouching Or Shifting
