The following LinkedIn post reminded me of the long standing problem with SAP Community profiles.
The problem is that you can not consolidate your badges or reputation points while linking profiles. The #profile_linking reads:
Linking does not combine the profiles in any way or consolidate the content list or the reputation
That is a huge problem, especially for the most active SAP Community contributors as they are going to lose all their reputation points and badges when changing jobs and can not access their S-users anymore.
