We recently implemented the Ideas portal internally and externally. Every day since, are getting many internal user Ideas getting flagged as spam. It would be beneficial to have the ability to white list users, so their Ideas will not continue to get flagged as spam. This is definitely a huge annoyance.
The spam check is no longer run on feedback from verified internal users in a portal. Internal users are those with an email domain that matches the domain entered in Portal settings > Users > Internal. We also have an improvement planned so that marking a user's idea as 'not spam' will automatically whitelist them going forward.
