Jarvee unfollow options

Hi, I'm currently using Jarvee to F/uF but i was wondering whether Jarvee stores a database of all the followers that have unfollowed me so Jarvee doesn't bother them anymore.

So my question is does Jarvee do this automatically? as in built in system?or do I need to manually enable this setting? Please can someone shed some light on this. Thank you

I believe its built in
