After further investigation the keywords (email, address, verification etc) are not picked up from the code but from the REPLY FORM, from strings like:
"Your name to display (optional):"
"Email me at this address if a comment is added after mine:"
"Privacy: Your email address will only be used for sending these notifications."
It is very hard for me to believe that google can make such a mistake. This situation is very common in all forums, website templates etc.
What are your comments and proposed solutions to this?
