Haha, it's just as friendly as Blockland.
If anything, Blockland offers a much better website and forum.
Also, you can't control what anyone does online, there are no swear filters and if some little 5 year old kid just happens to be playing in some brown town role playing server, there will be swearing and such, and you can't control that.
Blockland on the other hand, contains swear filters that you can turn on and off, and overall a much better server system.
Let me remind you once more that this is the new Blockland, it is being sold for approx. $20 and much has changed.
A flaw in your chat management is that it cannot be turned off if the user is in "under 13 mode" and he will not be able to see what anyone types, which can cause many misunderstandings and problems.
