Well you entered Omicron Kappa, which is restricted by the PRIME AI. But you didn't leave it at that, but also directly went to Planet Gammu, which is basically a sacrilege in the eyes of the PRIME AI. We also asked you multiple times to leave the system and told you what the consequences were.
We always follow the same protocol: If someone follows our demands and chooses to cooperate, they will be left alone. If they choose not to do so, the harvesting protocol is initiated.
