Even if a DT reviews the Gambling service there are two ways of reacting to it.
1. After reviewing, if the DT puts some positive trust on the profile. This is surely a shady activity from both parties.
2. After reviewing, if the DT just vouches for the service and does not use any trust rating. Or reacts to it as LoyceV reacted
here by giving a feedback from a non DT alt would be a decent way around.
