Minor trust score algorithm change

[redsn0w]

??? is a valid score in the new algorithm.

...

Then at least he doesn't have a "negative" trust red score but a pink one ... really cool.



Thanks again for the reply.

There are some useful changes, but the first score needs to be rescaled. It varies too much if one trust is added or removed. Makes anyone in Default trust much more powerful and those outside it more worthless.

Muhammed Zakir's rating shows as ???

already reported about this ?? ? bug to admin theymos

The code is : if(score < 0)
         return ?? ? (orange)

Hence it returned ?? ?

Ah, I think its not a bug but a new trust symbol

Edit: admin theymos confirmed this, new trust symbol ?? ?

@theymos what is the thinking behind increasing the numbers? It makes changes too much. Was it to increase the strength of DefaultTrust?

Currently, even 1 trade with a DefaultTrust means becoming green soon. Earlier one had to wait a lot of time to become green trusted. It also makes changes abrupt. Muhammed Zakir went from ??? to +5 with one change in feedback.

It looks like no matter what if the last feedback you receive is negative then you will either have a ?? ? Trust score or a negative score. Look at TECSHARE for example, his rating from Vod means he has a question mark rating.

Also TF has a negative 9999 rating lol.

not always
I have seen users who received both positive and negative feedbacks and still has black trust ratings with first number 0


Edit: looks like trust system is not completely done, i have a seen a user who received 2 positive trusts around 6 months ago and few later as well as few negative feedback but still his trust rating is black with first number Zero (0). it should be either green or red because trust ratings are old. also total number of users who sent him trust are higher on his trust page then shown in third number in trust score

I was freaked at first to see the change but then i looked up in Meta to find this.
Though am not disappointed but the previous Algo was better.

There is no decay. Ratings grow in weight from 1 to 10, then stay at 10 forever. (If the rated person has no negatives.)

Oh derp, I thought "months since rating" would be counting down for some reason.

Correct. Your trust network is assumed to consist of people who are basically reasonable. So if any trusted ratings are negative (which means "this person is probably a scammer, watch out!"), then this should be taken very seriously. That's why a single negative rating can easily cause a loss of 100+ trust points in this new algorithm. And if the most recent rating is negative, then this is a strong indicator that the person may have been running a long con which has turned into a full-blown scam.

If anyone is abusing this by reposting negative trust unnecessarily or giving out negative trust too easily, then you should remove them from your trust network.

You'll get used to the larger numbers. DefaultTrust doesn't get any sort of advantage as far as I can tell.

yes. you trust is still black while you have 6 months old positive trust ratings

Looks like Tecshare will have something to converse again about But all jokes aside, why does his show up as this for me? A bug in the system?

What is the issue with the earlier numbers?

DefaultTrust gets an advantage. Earlier, one default feedback still means 10 months remaining black and slowly increasing number. Now, all one has to do is manage one default feedback and very soon it is green. Similar is the case for moving from light green to dark green.

Advantages of trading with DefaultTrust members went up even more, they are going to get bargains now.

@ redsn0w
@ chronicsky

you see marco's rating green because you left him positive feedbacks also
Me and other users who doesn't left him positive feedbacks see it in black, not green
Trust:   0: -2 / +4

The meaning of having "green" trust is now diminished and will be similar to what was previously the meaning of having black positive trust.

Theymos cleared it before

If someone has 1 positive and 1 negative, then the time doesn't matter. They'll have a score of -1.

Examples:
Old -> New
+ - : -1
- + : -1
+ + - : ???
+ - + : 0
- + + : 1
+ + + : >=3
- - + : -3
+ - - : -3
- - - : -8

ohk! first i though that could be it but i never though redsnow left him feedback

@bold: This may lead to an abuse of feedback left by Default Trust members. I can't imagine now how one scammers account will look like with the max limit being 9999.

Is it possible to have a notification when a feedback is left? If not, it would be useful if the feedback system has a time attached to the date. It helps to know when a person was left a feedback if there are many members who have left a  feedback on the same day.

Yes. I think with this new algorithm low positive trust should be shown as black (maybe bold). Light green should be used when reaching some value (at least 5, maybe 10) and dark green when surpassing at least 2x or 3x that first threshold.
