reason being there decisions array way mistyped

decisions:
 - type: ban
 - duration: 4h

What did you expect to happen?

For the program to handle this improper decisions array and warn the user or bail at startup time with a invalid configuration

How can we reproduce it (as minimally and precisely as possible)?

Alter the default profiles to have

decisions:
 - type: ban
 - duration: 4h

Then generate a decision from normal processing

Anything else we need to know?
