Truly Anonymous Survey Responses
Currently, forms/surveys with respondent access level set to "Anonymous" are not truly anonymous. If a registered user is logged in when accessing a form/survey, their name, email, and other personal information are displayed in the response. The only workaround at the moment is to provide a disclaimer at the beginning of the form/survey reminding registered users to log out prior to submitting their response.
Should at least put comment that surveys are not anonymous on the form.
