For me, i delete those who are inactive for 14 days. Some of my comrades neither send F/AWs nor visit castle but i still keep them becuase they are still log in.

And you can try my method. Send request to all newbie (or sb you like) you run into while doing map. After 1 day, if they dont reply, cancel your request. In furture, if you dont like them anymore (they send nothing to you or sth like that), just delete them.

In the end, its up to you.
