Blacklist for player names? #62
Description
What is missing from the application? Please describe.
Currently players can use any name they like, which could be abused.
Describe the solution you'd like
I'd love a quick check against a "naughty words" list that prevents the player from creating an inappropriate name.
Additional context
I know this isn't foolproof, as people can get creative using unicode characters and so on, but it might be nice to make it a little more difficult than it is.
