A lot of scammers will be roaming free..
Not "a lot", most of them were tagged by other DT members(like ibminer,vod,etcetra).As for the others, I am sure Quickseller will come up with a good solution to filter them out.
Getting a negative trust was the most looked down thing before the tyranny of Lauda.He(it) was tagging people for their personal opinion too! Red trust was losing its value, it was turning into a cliche.
