They might have been thinking with only gold spammers in mind, but that will actually screw and probably deter new players, being under lvl10 and not being able to ask for help because can't use chat channels.
In my opinion a better fix is to automatically ignore any messages with certain parameters in them, like filtering, anything with the word gold, com, $, 3 W's (cause if you filter www they'll just type w w w), and other words they use in their spams that players wouldn't normally use below lvl10.
Also being a "westernized" version, they should have name restrictions too, I don't know how they would work that, but it's pretty obvious someone called Afklmnnljds is a random name created to spam, no one in their right mind (aka dis might do it

) would lvl to 50 with names like that and play actively hoping to build a good rep.
