1 - Who is going to verify that every link is accurate?
2 - So if a scammer just ignores that thread, they can't be tagged?
1. System will check whether both of them have replied in the respective thread. For example, I have created a thread in marketplace for buying something. You as a NON-DT member can only provide feedback if you have replied in that thread. Now, if some random person gave feedback, it will be same as of now. No one gonna care.
2. If a scammer don't create a thread even, or don't make a reply in any thread, how will we even know that he is scammer. Also, DT can provide feedback. And the link will verify the proof.
I just have mentioned that I have observed this system in another forum although there was no DT in that forum, lol.
If someone is offering a ROI of 50% a day or advertising a bitcoin doubler, you don't need a trade to take place to know they are a scammer.
Again, point 2 can handle this. If someone offers such kinda ROI with a thread, feedback can be given easily by DT.
