the problem is that some nicks are 'vulgar' in some languages. It is impossible to translate every word and exclude/remove them from the forum.
For an example, in Holland the name "Dick" is normal. Its just a name, but when you read it here, you probably think of something else... dirty minds!
So, what if a normal user, does like me, and enters his frontname? I think users will already look odd at this guy...
Can someone post me some names which are 'vulgar'?
