Closest I got is an ISD statement, which makes it clear either simultaneous alphas and simultaneous Omega+Alpha are illegal.
Awoxing is not illegal.
Repeated biomassing of characters can be construed as illegal if it is done to avoid certain consequences.
Abandoning an account, however, is not illegal.
Rule of thumb, is its the player that has signed EULA/TOS, not the characters.
The characters are just an extension of the player. The player is punished for transgressions, not the character.
In your case, I dont yet see evidence the awoxing alpha is run by the same player as the incoming fleet, simultaneously, albeit they are certainly working together.
