I still vote for player controlled game. When spammer is many blocked, the status will turn in pvp enabled mode. Then we can kick the spammer to dead.
To make it possible, at least 50 blocks is needed or so. That is big vote against one spammer.
The vote counter will reset each one hour (starting with first block), to prevent false vote count up.
Censor filter is still weak and can block easy normal words. Have seen already text errors, thus censor filter will not work.
But there is now spamming with Shout channel. Because Shout is not free, how come spammer can use Shout channel? Then there is some leak in the server so they can send free Shouts. Not fair, because paid Shout was good idea to prevent spam. But there is already leak or hole found to use Shout free.
