Would you trust someone who admitted to downloading child porn? I sure wouldn't.
I wouldn't but
1. I don't know if that particular statement was sarcasm or not
2. I don't know why the person said that
3. I have never traded with the person
IF I leave red trust based on my negative feelings towards that statement/user, I'd have to tag everyone red here all day long cause I wouldn't trust most people based on some of the things they say.

Feel free to do that then. You're allowed to leave a trust rating for any reason at all and no one can stop you. If you disagree with an individual's ratings, exclude them from your trust list. If you think Vod's ratings shouldn't be under DT, take it up with dooglus (he is on his trust list) or get another member from level 1 to exclude him from their list (HostFat already does). There is nothing else you can do.
By the way, if DT members only left ratings on people they had directly traded with, most scammers wouldn't show up red. I hope you see why this would be a bad thing.
