In Bad Behavior 1.2.1, a new feature was implemented which blocked the IP address of a spammer for 48 hours. As it turns out, this is too long for some, too short for others. The new version takes a more balanced approach. Now, if a spammer is blocked, its IP address is blocked for 10 minutes. If another attempt is received, the block is doubled to 20 minutes. And so on, without limit.
