I'm not a fun of random 100 users will be on DT1, even if the "unlucky" will be out of the DT1 the DT2 included on the DT1 inclusion list will be out of the list and some scammer will have a clean trust for an "x" amount of time.
Maybe a slightly harder requirement to be on DT1 is a good solution to reduce the list?
More merit? More people inclusion required?
Id agree to both of the bolded. Something like at least 500 earned merit & at least 10 fellow DT1 members trusting you.
