Is shooting a POB to prevent docking a violation?

[Alestone]

i think he means shooting a base to put shields up to stop another player from docking, i agree that it is not nice, and should allow the player thats authorised to dock to still dock when shields are up

There are times and places where being able to prevent someone from docking on a station via that mechanic is extremely useful.

Oh, certainly. The pirates find it a great help to have the game mechanic work in their favor by having control of the on/off switch for the shields of a base that they don't own.
