Here is a quote from the League Timing Rules:
_5 - Posting Schedule
5a - Time Limits - There is a 72 hour time limit per move. This (72) may be negotiated by the players at game start. If you agree to different time limits, you need to post it at the beginning of the game thread for the moderators to enforce.
For good sportsmanship, you should give defender decisions (casualty choices, scramble/intercept/submerge/kamikaze decisions) to your opponent as soon as possible.
5b - Vacations - Play can be paused for a total of 21 days, for whatever reason, without penalty by simply posting the need for a vacation. Please specify the duration of your absence in your game.
5c - Weekend Players. If you can only play on the weekend or on certain days, please state so when you are looking for an opponent, and clearly specify this in the game thread.
5d - 72 hour warnings: If 72 hours goes by and there is no game-play post from your opponent (i.e. at least a game decision made), simply post “bump” and the number of the bump (Bump#1, Bump #2, or Bump #3), which creates the “warning”. (Note: only post “bump” in your warnings to make it clear you are issuing a warning. Do not add any other text in your warning post.)
5e - “Bump” warning and consequences - Each “bump” warning resets the clock for another 72 hrs. However, on the 4th “bump” warning the offending player will be disqualified and declared the loser for that game. (Note: You get only 3 warnings per game.) You must post the warning when it happens (or before the next move has been made by your opponent). You cannot retroactively issue a “bump” warning. “Bump” warnings can be issued for posting of partial turns (for example, someone only posted their combat move), OOL requests, map questions, etc. but they follow the same 72 hour requirement.
5f - If a turn is not posted within 14 days of either the previous turn post (or request for decision on casualty choice, scrambling, kamikaze, etcetera) or the end of a predetermined “vacation”, then the player failing to post may be declared in default and lose the game. The 14 days may also be changed by mutual agreement of the players at the beginning of the game, if posted to the game thread._
So, the 4th bump is final (not 3rd) and 14 days instead of 9.
