As a newbie & lower ranks, all I did was argue about shitcoins with people 

I remember being slammed with a negative trust by a scamcoin developer who had somehow landed on DT. Yes I was a ferocious troll (also temp banned for that early on) and used to say nasty things to all sorts of people. Then I got them to remove it after a while, I forget how, but the trust system was a much more exclusive club back then.

I didn't join my 1st sig campaign until 2018 and didn't do many trades so I never really cared about the trust system until that point, which was around the time theymos "democratized" it.
