It would be better option if others DT tag them those have tagged by Lauda. But I think its not possible as well. On the other hand, as far as I know Lauda removed DT1 multiple time and someone put back again. I think same thing will happen again. So there is nothing celebrate for scammers.
It would probably be an even better option to verify that anyone someone is considering leaving negative trust that they are in fact a scammer (or someone who will likely scam in the future). They shouldnt leave a negative rating just because lauda says the are a scammer without evidence.
