Technically the 5th battle there would be a violation (particularly if any of battles 1-3 were from the same ally)
However,
1) in all cases if there are no complaints (including no history of complaints about the same actors), then no action will be taken
2) the first offense is usually let stand to give the digger the benefit of the doubt that their actions have a reasonable legitimate purpose
And 3) the Fort Battle Team is empowered to exercise discretion where in their judgment intervention or non-intervention is in the best interests of the community, particularly during times of event currency
For the particular scenario you describe, it would be preferable that the fifth battle be scheduled within 10 minutes of the fourth battle. This prevents players being able to attend both battles, so avoids the possibility that the battles are considered push battles.
