My forum has a lot of spam members registered.  My spam protection settings usually will keep them from posting.  

I wondered if there was a way to flag some key words that would require their membership to need approval from an admin?     (For example these type of key words: slots, bitcoin, gambling…and other adult entertainment key words)

if possible, where do I do this?   I have searched but didn’t see this option. 

Thank you for your feedback and suggestions!
