I'm sorry but I doesn't understand what you mean,
But you don't know the identity of the receiver of the forwarded email.
You only see which token is used. You don't need to use token and open the survey via a generic link.
What he meant is that, suppose you have emails to a lot of persons and use a token table with unique tokens where every person have one unique token each. If person A gets an invite but then forward that email to another random dude called person B you will still think person A answered the survey of that specific token. There's no way you can really know that person A answered the survey if you don't include some kind of personal question, like birth date (if you have the birth date of each person), of course, if person B knows person A's birth date you couldn't tell from whom the answer is coming from.
And as mentioned above, people can forward their invites and someone else can answer, but yet again, you will still think the answer belongs to 'John' if there's no personal questions in the survey that can identify the one that answer.
