Ignore all the comments and read from here.
There is no point in arguing since you didn't know how to use the system properly. So arguing with them will make you look bad only.
You need to know one thing to understand whom to add and whom to exclude.

- If you see someone's judgment is good, they have a good trust list, and they leave accurate feedback. = Add them to your trust list.
- If you see someone create good content = Merit their content.
- If you had done any deal with anyone where you had risk to lose, but the deal went smoothly and you also think he is unlikely to scam = Leave a positive feedback.
- If you see someone scammed others or scammed you, or see the attempt of scams = Leave a negative feedback.

You're welcome
