Thanks for the reply. Yeah, I did read that article, and followed the link in there to this page
https://www.phpbb.com/support/docs/en/3 ... mmer-tool/ -- and that's what I'm trying to do. "spammer_prevent" was one of the existing custom fields but maybe a previous forum admin set it up awhile ago. I did create my own custom field and had the same problem with the private label being displayed in the same fashion as the screenshot.
We're already using the Q&A method, but a fair number of spammers are getting through it. We have to keep the questions simple, since our audience includes young people, and young people with limited English skills, and that maybe explain it. So I was hoping to set up this alternate method, but have the problem in my first post.
