Since you mentioned Laszlo here, we are aware that the profile woke up after many years and i think they haven't made a post but supposing he was to be a DT member, can we tell if his reputation years ago will still remain the same now? what if he has a questionable character now and has ulterior motives for coming back to the forum don't you think that many people can fall for his trap due to the idea that he has a past reputation that was trusted by many?
You need to learn how DT works. If you know how it works, your question answered.
DT1 is added manually by Theymos. He selected the DT1 members from DT2.I stand to be corrected but I think this is not accurate.
Theymos don't manually add DT1, it's the algorithm that determine DT1 based on the criteria listed on this thread
here in where he point as #3.
Theymos itself is a DT1 like every other membes the algorithm selected, if he manually add you to his Trust list doesn't make you DT1, you will be DT2 just like how other DT1 that make their trust list to have DT2.
However, Theymos can remove DT1 if only they are abusing the system.
