Some who try to interact with the Zuma are responded to. Some aren't. This is not some whim, there is reason behind it which is quite clear and obvious if people bother to try and work it out.
I am not going to change the character of the Zuma because some people are frustrated they seem to get nothing from them or do not understand the point of them. Nor am I going to explain in Out of Character forums the reasons behind actions that some players are fully aware of.
If you want answers and interaction from the Zuma, learn how to deal with them and find out in game. Remember, you came to the Zuma first, they did not go to visit the humans. Also remember that it is not just some human realm run in the same way as human realms.
