@Irishman81 I was just curious about your reasoning, nothing more.
For me, HC is a casually-played game (less played with the nation war debacle, sadly), and I appreciate that my townsfolks can be away for a bit (as real life sometimes dictates with family, work, school, and stuff) and that they 1) count towards the town size (so I don't lose chunks), and 2) they know that their town will still be there in the unlikely event that all of us are away for an extended period of time....
I guess I am missing how a positive punisher (if you don't log in for 30 days, your town is going to get decommissioned) encourages the kind of participation that really creates veteran players who will stick around. Positive reinforcement definitely is the way to go, especially with the age of HC's target population. (See B.F. Skinner's operant conditioning for more on positive/negative punisher/reinforcers). I suggest that HC stay a place of reward for participation rather than punishing those who are away for a while.
