Effective immediately, the following clarification has been altered:
Bug using is, but not limited to these examples:
Any fleet actions towards the defender 20 seconds before an attack
Using any method to generate lag for a player in order to prevent them from sending, recalling, or slowing their fleet is not permitted. One example of this is any mission not capable of destroying the fleet which reaches the planet or moon under attack within the last 20 seconds of the attack. In this case, it does not matter who sent the fleet.
