Forbidden words are more like substrings are they?

Hello,

CB provides a means to declare comma-delimited "bad words" (from whatever source) as text field parameters for reg and profile edits.
However, those words turn out to be managed as substrings as well and not only as comma-delimited words.

A lot of of my members were simply unable to register their address.
Why? Forbidden word "ass" is a substring of "Strasse" which means "street" in german.

I think to consider forbidden words as a substring of any word is too restrictive.

Who has experience implementing "bad words" and to spend some thoughts about to handle this?

Thank you in advance.

If any occurrence of the word appears in the supplied string it will error. It's not breaking the input into words then checking each word individually. We have no such usage. Suppose you could use CB Code Field, which provides a Code validation usage where you can supply your own PHP for validating a fields value and there you could add your word by word validation.
