I've now taken more time to analyse it and realized there still are way to many users added by him that have left positive trust to him and have little other reasons to be there. I don't think they deserve to be DT2 and so I've decided to re-exclude willi9974. I can't say he is wrong at deciding whom to add into his list but I do say I strongly disagree with his requirements to add someone as DT2.
Being on DT1 means choosing DT2 users and under that logic I don't think willi9974 should be DT1
I echo the sentiments of EcuaMobi after reviewing the users myself.
