May I suggest you check the [url=
http://www.proz.com/?sp=agency_list&viewPage=faq]Blue Board FAQ[/url]? I have quoted some of the relevant wording below.
Why are agencies in the Blueboard if only stay the Address?
Generally, if members would like information about a particular outsourcer that is not yet listed in the BB, they are welcome to enter that outsourcer, and to invite others (who have worked for that outsourcer) to comment.
More specifically, a group of moderators dedicated to the Jobs Area attempt to create BB entries for each new job poster. The point is to enhance transparency.
BB FAQ #1: ProZ.com members use the Blue Board both to rate their likelihood of working again with clients they have worked with at least once, or to solicit such information from other members.
I thought that in BB are only agencies that already have been controlled
Careful here: the fact that an outsourcer is listed in the Blue Board means nothing per se - there is no controlling or vetting mechanism involved. However, when moderators or site staff notice several negative comments involving non-payment, we may become active, and have done so repeatedly.
BB FAQ #10: How reliable is the Blue Board?
The reviews posted here are not confirmed in any way, and represent the opinions of the reviewers only. Things to consider when evaluating reviews are the activity levels, identity verification status, membership levels, registration numbers and other characteristics of the reviewers.
Notwithstanding the reviews posted here, members are encouraged to form their own opinions from their experiences in working with, or negotiating with, clients directly.
