Maybe red trust sounds a little strickly but he doesn't deserves positive trust which TheButterZone left on him.
Is he even in the DT? (too lazy to check)
As for OP PMing me to post here, I don't disagree with Lauda's reasoning for the neg and from what I see there was no valid reason for repaying the loan so late neither was there any communication. If it were me I'd keep up the neg for a month(after it was given) and if any shady behavior hasn't been seen since, remove it , but thats just me.
