I know cygan from our German section and he's a honest member from what I've seen. He has made great contributions to our forum.
Yes, adding other accounts to our own DT list, especially as a DT1 (which will make added accounts immediately DT2 members), should be considered very well and if these accounts have not left any substantial feedback other than positive feedback to the DT1 member who added them to his trust list, there's not reason to have these members in DT2.
I'm sure cygan isn't aware of this and his intent wasn't malicious at all but it's a bold statement statement from OP that cygan would "abuse" DT.
It just seems to be a misunderstanding that cygan is not aware, that his inclusions are promoting all accounts into DT2 position, which can be abused easily if one of these DT2 accounts turns out to be a scammer.
