I would like to know the reason why people have negative trust on their profile.
It is because they might done some illegal or prohibited stuffs here in the Forum.
Here are some of my opinions why a certain Member is given a
Negative Trust .
1.
Scammed people once or so many times (If ever that someone has been reported and proved that he/she Scammed people here in the Forum, he will be automatically tagged with Negative Trust by our Moderators/DT Members.)
2.
Spamming (As we can see, Spamming here in the Forum is strictly prohibited, if someone has been reported that he/she is spamming, the account will be automatically banned or will be given a first Warning. But if the account user keep posting spams he will be tagged with Negative Trust.)
3.
Selling/Buying account ( Buying and Selling account is also violating our Forum's rules. With just offering that you want to buy account or sell account can cause your account to being tagged with Negative Trust. See for example here
https://bitcointalk.org/index.php?topic=3195218.msg33124738#msg33124738 The OP is looking for someone who want to sell a Sr. Account and unfortunately a Jr. Member responded thats why both of them are given Negative Trust).
4.
Destroying DT Member's image ( I believed that some members here used to destroy Moderators and other DT1's image that why they're being tagged with Negative Trust.)
5.
For violating rules multiple times (This is obviously the first reason why some members are given Negative Trust. It is because they always violate rules over and over again.)
Well, I know I didn't listed all reasons. But I hope it helps you out. But I also believed that not because a member is tagged with Negative Trust doesn't mean that we will underestimate them, we should still respect them.
