@SteTaylor, the problem – and the reason why name banning alone is no solution – is that there are literally unlimited different names to make. I can add any number of invisible characters to a name: 1, or 2, or 3, or 4, or 5, or … You get the point.
It is simply annoying to ban a spoof-name just to see a new one pop-up. And this new one will look *exactly* the same. Your forum users will not see the difference between the previously banned name and the newly spoofed one.
