I would (on hindsight) propose just banning her indefinitely again (if that were possible, subject to a proper discussion with all admins/masters).
It is still uncertain the actual extent of her involvement and to which extent she abetted/aided them in doing it. We already know that a handful of known players had also asked Ownz to hose down other servers they didnt like... so this is just a repeat. Coupled with the fact some idiots have being going around threatening ddos attacks...and following through with it.. its pretty messed-up.
In my opinion if kita-x had not enticed whoever it was behind the outages, none of these outages would have taken place to begin with. And , no other servers would have taken a hit as well.
One flood is generous enough (more than enough imo) to send us a 'message' but it went beyond the ''legal'' 1-hour of outage.
And if she had the balls for it..she , given her experience in this field could have just used her own booting resources to hose it down (and face the repercussions) instead of talking directly to that troublemaker.
