You want to be added in DT trust? Just leave sportsbet.io a positive trust here
https://bitcointalk.org/index.php?action=trust;u=832366(example - see Rohang left trust feedback for them and got added to the DT courtesy LFC_Bitcoin) no one knows this guy and has no trades,etc but he gets added to DT
@LFC_Bitcoin I have also given them trust so please add me in DT
good chance to get yourself added in DT

ROFL. Any DT can put a user in there trustist based on there own judgement even though they don't have any public transactions with them. Maybe Rohang is closed to LFC in private. Theymos didn't mention any requirements on including some user to his/her trust list so this move is legal.
This is just my assumption. Maybe Rohang is an account of a sportsbet hardcore player that invited to post here in the forum.
