A proper process must be done and thorough investigation is a must before tagging someone, I must agree that leaving a negative feedback without a hard evidence to support a claim is somehow improper and inhumane.
That's why when I tag someone (although my tagging does not count since I am not a DT member) with redTrust I leave proper evidence with option of a second chance.
1. The idea is with proper evidence mark someone with red trust.
2a. When they notice they will come back to you with evidence that they are not abusing merit. You remove the red trust once convinced
2a. They may come back to you saying it was a mistake by them (they come up with all these funny excuses. i.e: Not aware, friends account, I am a student give me another chance etc etc) and they won't do it again then give them a second chance.
Keep a log of them admitting their mistake (What I thought is best, to give them a neutral trust with having saying that the user made their first mistake and admitted it and committed that they will never do the same)
3. Remove the red trust.
with enough evidence.
This is how I am dealing now.

Caution: Don't try it with your main account unless you are DT or them kind of member. You don't want to see your account is red tagged like me
