Well...people have gotten Negative Feedback's for writing scripts for Ponzi's (example BSM) which is considered equally punishable under the DT's laws.CryotoDevil who's a DT under Dooglus takes the initiative of negging ponzi users which is a good thing.Not sure how to reach to the above situation .
If you agree that negative feedback is appropriate for those that write scripts for ponzis then I would suggest that you leave dooglus a negative trust rating.
Since you generally need to trust those who are in your trust network (to a certain extent), I would also suggest that you exclude dooglus from your trust network by adding the following to your trust list:
~dooglus
