Abusing a bug that involves the attack system to blind the enemy, in paticular to just annoy rather then hurt is bug abuse. Though doing it to even blind their attack list without the intent to attack is bug abuse since this is a bug and bug abuse is against the TOS.
Playing fairly and Honestly
Astro Galaxy upholds high standards of moral behavior. Any player who is caught manipulating bugs in the game or has been cheating in any other way will be deleted from the game immediately. Using vulgar words towards other players may also lead to deletion.
That said we all know SirEmi doesn't actually enforce this. I would rather just see this bug fixed.
