They only react to tickets, and only if a lot os people complaim about the same construction. And i think they do it only time to time, some times an admin show up to run the punishments, them we have a long period, till them show up again. Theres is no active adm at all. About the limits they never showed any intention till the moment to limit building pieces, maybe it will negativelly afect the sales of set on bazaar. I believe most of buyers from bazaar ar official server players, due to in private server with mods you can access an near infinite stuff even better than bazaar. By the way theres no much official information about it, and most off people share their personal experiences.
