As I recall, Gand had been in Centara a while before stealing it, which meant it wasn't infiltration, just looting. What's at issue here is the infiltration rules, like Paps gave:
"1/ You May Not
Infiltrate another group with the intention of killing their members via any method other than a red scenario."
This is clearly what was done here, as this was Orphea's first and only act as a member of CSA, and he would have had to have all the GE people standing by to go.
In the past, Rav Isaar tried something like this. He was banned for it, and in the SimNews, it was stated:
"Ban and clarification about spying rules
Rav Isaar has been banned for breaking the spying rules. He infiltrated Raptor Pirates to get members of the group arrested by Eidola...So there was a plan to have Rav join the Raptor Pirates with a harmful intention and this clearly is infiltration
, no matter if any information was passed to anyone outside the group while Rav was a member of Raptor Pirates."
These were the rules posted and I took them at face value. Those were the rules I assumed were true when CSA accepted Orphea as a member. I would be sorely disappointed if the Administrators decided to ignore this.
