if you go into a highly complex environment with countless rules, how do you know you are not accidentally breaking one without knowing it?
Ignorantia juris non excusati was just asking weather its possible to exchange merit donations, didnt knew it was illegal, the mods should here use their brain:
None of the users who gave you a negative trust are mods. Merit trading isn't even against the rules. It's just a shady behavior, and that's why you got a negative trust and not a ban.
2. "I just don't trust him" is a completely subjective oppinion, similar like the central banks and banking cartels that "I just don't trust Bitcoin"
Maybe. But trust isn't moderated. The user don't trust you and that's it.
and remove this negative trust.
Only who left you the negative trust can remove it. And after reading the reference link, I doubt they will.
