Fighting spam bots chatting. My suggestions are: - Limit the number of messages shout / trade to 10 per day per person. - Increase to 5 or 10 minutes between messages in shout / trade. - Activate the report of bots within cities and zones of peace. - Increase the minimum level necessary to use shout / trade 30. - Ban all accounts that have used IP bot. Also players who have purchased other illegal users.
