Rating idea is decent, but im sure codeshops will still get 90% positive like ratio and still get high quantity of likes.
1. Admins should manually handpick houses that are decorated, fancy and put 6 of those up for the recommended list for a week.
2. A strict filter system. Must apply which category your house belong to. So we can filter out codeshops to find themed ones. Wrong category houses can be reported for a warning. If they get too many warning for being in a wrong category. Their house will forcefully set to private for a week.
