I think I'm still in DT, although I haven't even bothered to check lately, so I guess it will show.
Even if you're currently not on the DT list (and I have no idea where I or anyone else stand, either), my suggestion is to still leave feedback as if you are--because chances are that with the rotating system you'll end up on it again eventually and it will light things up bright red for anyone you've tagged. I'm probably telling you what you already know, but thought I'd say it anyway.
It is not clear to me why he was not red tagged at the time for borrowing without collateral, when it is standard practice on the lending board.
Vod used to do that consistently, but I can't even remember the last time I visited the lending section. I always thought getting tagged for asking for a no-collateral loan was extremely harsh, because it really ought to be an issue between the borrower and any potential lender, and I've seen plenty of green-trusted members who've done it with no consequences. A warning given within such a thread would be more appropriate IMO, but that's just me.
People should really start putting Reference links on their negative feedback, without that, it can never become Trusted.
Agree 100%. If I'm looking at a wall of red trust and none of them have valid reference links, I'm inclined to believe they're retaliatory (*ahem* take a look at my trust page for instance). Without a way to validate whether someone deserves a negative, it's a waste of time giving one IMO.
