registration censor problem
 

Someone signed up today with a foul word as the username, achieved by putting spaces in between the letters whereas without spaces, that word is already censored in the admincdp > vboptions > user registration options area.

So the question is, how can I censor the same word with spaces? The setup is that each keyword must be separated by spaces.

Just ban/delete the user - they will always find a way if they want to. (Well not always, but you get the point.)

What about regex? I'm not expertised with regex expressions but wouldn't that at least help?

Yes - but you'd need to scan every single person that registers, and regex functions are amongst some of the slowest in PHP.
