Any tweaking would lead to more information for lenders,which would lead to less loans funded.
We all know they don't want that.
What they want is for the maximum number of listings up, rather than tiers where some listings are obviously bad or downright fradulent while others are reasonable.
They got rid of City, they got rid of vetting (few will do quality work for free), they won't verify income, they discourage borrowers to use PII, they limit communication on their forums by censorship and slow moderation.
Instead of cracking down on the frauds, they are cracking down on the quality listings, trying to bring them down to the same level of homogenous mediocrity.
Imagine a grocery store doing this--instead of removing the rotten produce, they take away the fresh organic vegetables thinking that customers will not see such a wide difference in quality and that they'll sell more produce that way.
