It says in his trust that this account is either sold or hacked, but this account is still a valid DT2. Is that normal or what?
The account is included by TECSHARE:
For the record: TECSHARE included him
more than a year ago, while the negative feedback appeared less than half a year ago. TECSHARE should check this

I noticed this case too when I posted the lists. I can create a weekly list of all DT-members with one or more negative feedbacks, but that will also include many users who have a lot of positive feedback.
