The rules
Keep the ranking honest.
1 endorsement is the minimum.
Your $1 registration through your LinkedIn-connected account creates your first self-endorsement. Your answer to “Why do you choose this skill as your best?” appears with it.
Every additional $1 is one clear vouch.
Every completed $1 endorsement counts immediately in the ranking. Comments stay private until the profile owner approves them. Declining a comment does not remove the endorsement.
Endorse what you know.
Put your dollar behind work you have seen or trust firsthand—not a vague impression of the person.
One endorsement per person.
Your LinkedIn account gets one final $1 endorsement for each person. Choose the category that best represents the work you know.
No additional self-endorsements.
Your LinkedIn-authenticated registration is your one self-endorsement. After that, support must come from another person. Manipulated, fraudulent, refunded, or disputed payments can be removed from the ranking.
A signal, not a certification.
The ranking shows where people were willing to put a dollar behind someone’s work. It is not an independently verified professional credential.
