Free Signs too Free?

It does get aggervating with non op/admin players asking 24/7 when im on for a free sign. I usually let them have it if its like tools or wood or stone, ocassionally i will put a diamond sign but i say if we start to see the towering diamond buildings that are nothing but diamond we replace it with wood and get rid of the sign. Maby put that at the spawn that abusing the free signs we give them will resuslt in the signs being taken away. any other ideas?

Stop doing this please. Nobody should get their own personal free signs of any kind at all. The more you give stuff like this the more people will demand. And we get these player "shops" springing up where they'll trade this **** that they're getting free.
We'll never be able to manage this stuff if there are free signs spread accross the entire map -_-

I don't think a seperate world on the same server for legit would work, people would just carry resources from the other maps. Also we're never opening up the private, so don't worry about that.
