It's important to mention some differences in how the filters work for users who open their profiles and for users who check the profiles of other users.
Ideas. Users that check the profiles of other users see only the ideas submitted on public forums under the same portal and their quantity.
Votes. Users that check the profiles of other users see only the ideas that have been voted on public forums under the same portal and their quantity.
Comments. Users that check the profiles of other users see only the ideas that have been commented on public forums under the same portal and their quantity.
The information about private and support forums is only available for users in their own accounts. Thus, the data shown in the filters is different for a profile owner and a user who checks another user's profile.
