As a feature request you could ask phppp (newbb Dev) to incorperate a CAPTCHA, now this won't stop all spammers, but it will stop the spam bots, automated spammers.
Now this feature could be optional, and with further settings to:
+ Turn on for all users
+ Turn on for non-registered users
+ Turn on for registered users
+ Turn off.
Or I suppose an option to enable this feature as a requirement for specific groups, enabling group permission use.
Just an idea, like I said maybe make the request to phppp?
Although not a total cure, it could be a start.
Wikipedia:
CAPTCHAs are used to prevent bots from using various types of computing services or collecting certain types of sensitive information. Applications include preventing bots from taking part in online polls, registering for free email accounts (which may then be used to send spam) and collecting email addresses. CAPTCHAs can prevent bot-generated spam by requiring that the (unrecognized) sender pass a CAPTCHA test before the email message is delivered
