He will eventually drop from the DT list and his rating will become meaningless. For a while you’ll still flash red but it will eventually disappear. You shouldn’t worry about it that much. However, the fishy part here is verifying the death of this individual. Some forum users go dormant for a few years and come back later. You can’t assume that they are dead.
Thank you for this comment, after reading the op, i was interested to know the solution to what the op enquired about, i felt relieved after reading this comment, its indeed good to know that the trust system is a well thought out system that gives little to no room for forum users to abuse.
1. Is Negative Trust irreversible?
According to what i know which i guess alot of users have already stated, Yes, any trust, be it Negative, Positve or Neutral can only be reversed by the user who gave it, though like some persons here have said, Admin and moderators to have the ability to reverse whatever kind of trust you were tagged with, but they choose not to interfere so as to allow complete decentralization of the trust system.
2. At what rank can someone send a negative trust? (Newbie, member, Full, Sr, Hero or Legend)
Aside newbies which I am not sure if they are permitted to make use of the trust system, i think every ranks are eligible to use the ranking system.
3. How many negative trust can one send in a week, month, year or lifetime?
Answer is unlimited, there is no set number of Negative, Positive or Neutral trust one is permitted to give in a month, you can leave as many as possible if you wish.
