Personally I think the reputation thread was a better approach than the stars for precisely that reason - you have the opportunity to see both sides and how the rig owner handles issues. Star ratings are one-sided, and thus are subject to manipulation by renters (who are often competing rig owners themselves - hmmm, what could possibly go wrong?)
The star system is simpler for people in a hurry, but the downside of it being potentially unfair to rig owners should also be considered.
Can you make some
suggestions for improvement vs
blanket negative feedback regarding ratings? We cannot stay permanently attached to bitcointalk unless Thymos wants to sponsor or buy LeaseRig. We also have to have an onsite feedback system so customers outside of bitcointalk can easily see reviews.
It appears you gave the star system no stars which by your own admission:
