Do DT members get some sort of guidelines sent to them by theymos when they are added to DT1?
No.
nonnakip should have just gotten positive trust, and maybe multiple, based on various work or trades with Og/Nasty*. I feel like Og's response to nonnakip being added to DT2 may just be "Well, I trust him!".. which he may, but does the inclusion of nonnakip help the DT network, no. Does it hurt it? Short-term probably no, long-term may be debatable. Unless there are specific guidelines sent to DT1 members like Og* specifically stating all of this, it seems tough to deem this "DT abuse". Maybe I've missed it but I'm not sure I've ever really seen any public guidelines involving DT1 members and why they should or should not be adding people to DT2.
I would trust nonnakip to hold every cent I have and value his judgement more than any other human being alive. I've removed him because as stated, he doesn't leave trust for anyone so there is no current value there, but make no mistake that he would be on my trust list if he left any ratings for anyone other than myself.
