It is not a good reason to hamper someones ability to trade smoothly here, this is an open forum, discussed many times before and why is it that difficult for this type of users to use trust ratings to indicate scammer only? The rating I am talking about are on the people who have not scammed any funds, with no real victims. You know, it's even hard for some people around to accept apologise !
Hold your horses. Trust ratings can and should be used for a lot of stuff that isn't outright scamming, stop trying to define it how it suits you. If you want to go that route, just exclude Lauda and proceed on your merry way - you got your own trust system in your custom trust list.
But if you're talking about "ability to trade smoothly" then you're probably talking about DT and I doubt that even with scam-friendly weasels like TECSHARE in it we'll stoop down to the "do any shady shit just don't steal money" standard.
