The likelihood of Lauda removing a negative trust has historically been very very VERY small. Your options at this point are to "politely" PM then *ONCE*, presenting your case and then wait. If you hear nothing or they say NO, then you are basically shit out of luck
Admins will NOT remove the rating.
As for the "scam warning" on your thread(s)... that will show as long as someone on DT1 or DT2 (Default Trust) has left you a negative rating. It only shows for users who are not logged in (and possibly newbies). For instance, I don't see that warning unless I use a browser window where I'm not logged into the forum.
So, theoretically, if Lauda were no longer on DT... the warning would not show, regardless of whether or not they had left your negative trust. A lot of people have been trying for a long time to make this happen... The result: http://IsLaudaStillOnDT.tk/
Got it. Thank you so much for explaining it.
