It would work as designed if it allowed you to select something to replace the word/phrase you're attempting to block but it doesn't. As you say, that's only confusing because it's appearing in the UI for the server validations.
If it fails validation but doesn't replace it with anything then that would do wouldn't it? The validation would fail and we'd deliver an error message.
Phone number validation doesn't have an option for UK phone formats plus how can you rely on a user entering their phone number in the exact format for whatever country they're in?
What I'm basically trying to prevent is bots submitting the following:
Anything that would allow a bot to include a link to somewhere
We're receiving spam form submissions that have links in ALL of these fields. We've used Alphanumeric validation to prevent it in the name and telephone number fields, and we appreciate that there isn't much you can do about a bot submitting firstname.lastname@example.org (or whatever) as an e-mail address.
However, in a text box field I really want to prevent links being added and the only way I can see of doing that is preventing submission of words / phrases such as http:// or URL: and such like. I'd take your advice on how best to achieve that.
Oh, and one definite issue with this extension...it doesn't allow for line breaks in a text box and subsequently fails.
Appreciate the help, thank you.
