We made a big mistake, the survey has been set to be anonymous. Unfortunately, 365 answers later we discovered this problem and now i would like to ask if there is any option to connect the responses with the token set for this survey. I see that an user who already answered will see a message that he cannot use his token again, so i'm thinking that should be a connection between token and user and between user and answers? Can i create a query between some database tables in order to retrieve data?
The tokens are stored separately and marked as completed. To make sure actions like this can not be done timestamps are all the same so they are not going to help you. I think you are lost here.
