This is not my first experience with DDOS. It appears to me that some people take great joy in taking down another's game.
In another virtual world, I was accountant for a music stream provider. It is not like the company was making big $$. The first time, we changed the IP and cleaned up the mess...it lasted less that a week before the attack started again. We had made some changes, but it wasn't enough. The second time, we changed servers, the third time, we moved to a new data center. The fourth and last time, the data center made some magic with a another server that the attacks went to before the primary server. I am not a server expert, I am merely saying that sometimes, especially with a small company, it takes more than one change to protect against DDOS. Bad mouthing Lisa, Gizmo or the devs is just sour grapes. I am sure they are doing the best they can, every day we do without building (cause I know this isn't a sex game right?), they are losing money cause they are fighting the DDOS, paying $$ to try to correct the situation, losing members, not allowing new members to join and prolly the hardest thing ever to recover from: they are losing their reputation:(
Just my .02, for what it is worth.
