Its been less than 6 months since the last changes were made, I think theymos should wait another 6 months before fiddling with the system. People are still adapting to the last upheaval. To introduce more changes now would just add to the confusion.
I dont think the current implication is working. This is for many reasons.
My proposal should completely eliminate any trust disputes for controversial reasons. If someone starts leaving inaccurate ratings with inaccurate comments, they can be blacklisted.
If someone leaves a negative rating you do not believe makes the person a scammer, you are free to ignore it.
This is already the case. If you don't agree with a rating, ignore it or exclude the person who left it.
It is only possible to exclude someone from your own trust network. This will do nothing to address how others will view trust left by this person. As mentioned, the majority of businesses use the default settings so any rating left by anyone in DT, and if considering doing something such as giving an unsecured loan, looking at these ratings is logical.
Further, it is not possible to exclude an individual rating because all ratings are calculated in trust scores.
The calculation for if a warning is displayed doesnt need to be done by users and I dont see any major drawbacks if individuals dont understand this.
