I'd suggest to contact DT1 member who has included him on DT2, oh wait you can't do that because they are both the same person.
Here is the thing:
In this forum you need to earn the trust of already reputable members> DT1-2 members.
How could you do that?
Here is how:
You need to earn their trust by trading with them or by helping them > tagging people red for cheating in bounties, scamming etc.
Their trust or distrust is also visible by default and only their ratings matters, meaning if you help and trade with non-DT1-2 members, you are not trustworthy by default trust settings.
So you are left alone and untrustworthy if you don't earn the trust of DT1-2 members. OK.
Now DT1-2 members have proven themselves to the community to be trustworthy, therefore the community would deem their ratings as trustworthy by default. OK.
Here is the problem:
What happens if DT1-2 members make a mistake or try to settle personal quarrels with normal forum members by using their trusted ratings?
Answer to that question is:
Nothing would happen if you are not trusted by other DT1-2 members so that they could leave you a positive feedback to counter the negatives.
How would you earn the trust of those other DT1-2 members?
You would do trade with them, you would help them by tagging scammers and cheaters.
What is the problem here:
The problem is that people here have alt accounts and they could abuse the system, the problem is that there are factions doing whatever they want while they are doing entirely different things, all of them are trusted by one person> theymos a.k.a admin.
Do you see the contradiction now? theymos trusts DT1 members but some of the DT1 members say that they trust theymos but they would act completely opposite.
Where is the problem here?:
The problem is that there is no one common standard, there is only cartel-like operations running deep inside this community.
About this case, I believe that the red tag is well deserved. you asked to act as escrow in a community where only the trusted people could act as escrow, the same DT1-2 members. therefore the tag is legit.
