Could my SCN user be hacked? Received points for unknown activities

Hi,

After some period of inactivity in SCN I just wanted to create another blog. I was wondering about my rewarding points (seemed higher than I remembered. When I looked at the latest points I "earned"

I saw several entries about alleged Wiki pages that were created under my user name in several spaces during the last month. But I haven't posted/created anything for at least 2 months and surely not in spaces like Healthcare or ABAP. Any explanation? Could my user be hacked and abused?

Kind Regards

Volker
