How do you deal with inappropriate usernames?

[Heatman]

True. To solve it, this particular rule must be displayed as a caution when they are doing the registration at least.

The only problem is that most people that are making use of communities find it very difficult to go through the terms of service that they are supposed to identify with whenever they are using forums. This is because whenever they are well-informed about how they are supposed to behave, they may not be doing this kind of thing.
