There seem to be a substantial number of accounts that have registered with
obvious passwords, the same as their usernames. Recently, vandals have been
hijacking dormant accounts like this to vandalize and evade blocks. This is a
serious security threat since 1) it means vandals can get around any account
creation blocks by using old accounts created on other IPs, and 2) we are forced
to block compromised dormant accounts that are use for vandalism, even if they
have prior edit histories. The software should prevent such unsafe passwords.
