There are already guidelines, but not all seem to be aware about them. If it is neccessary to red tag low quality posts, you should discuss with Theymos to modify those guidelines.
I added a trust system to the marketplace sections. When you're logged in, you'll now see something like this next to Marketplace posts:
Trust: 1: -0 / +12(3)
The first number is the user's trust score calculated based on how consistently they've received positive feedback. Probably no one will get a score above 0 until the system has been around for at least a month. The second number is the number of reported scams. The third number increases with the number of positive reports, as does the fourth number in parenthesis, though the fourth number is more resistant to abuse. This text changes color depending on the score. Users with a negative score (attainable through scamming) get a red warning attached to their posts.
These scores are taken from your trust network. They are not global scores. You can edit your trust network here:
https://bitcointalk.org/index.php?action=trustIf your trust depth is set to 2 (the default), you will trust feedback by people you trust, people they trust, and people they trust. I might change the default in the future; we'll see how this works. Your trust list is public.
On feedback pages, you can leave trade feedback. There are no rules for this, but here are some guidelines:
- List all of the trades that you do with people (or at least the major ones). This is not like #bitcoin-otc where you give people just one score.
- Do not rate people based on the quality of their posts.
- Older ratings count for more, so don't delete old ratings if you can avoid it.
- "Risked BTC" is how much money you
could have lost if the person you're rating had turned out to be a scammer. Or, if they are a scammer, it's how much you lost. Use the BTC value at the time of reporting.
- It's OK to post a rating about the person in general, not tied to a specific trade.
- If you want to make a rating stronger, increase "Risked BTC". 50 extra risked BTC is equivalent to an additional rating.
If your trust list is totally empty, you trust "DefaultTrust", which includes some trustworthy people that I'll select. But if you add anyone to your trust list, even if they don't trust anyone, DefaultTrust will no longer be considered part of your trust list.
In the near future I'll add these same ratings to PMs.
Tell me if you see any bugs. I didn't test this much yet.
"Do not rate people based on the quality of their posts."
Or are these guidelines already modified?
Although there are many spammers around (posts can be deleted by moderators) it would protect against ruining accounts by subjective heavyweight feedbacks, if all DT members would pay attention to those guidelines.
Maybe it would be helpful to implement a rating system for post quality, that is led by members, who are not participants of signature campaigns and are qualified for judging posts.
