Why is gumshoo just for eBay buyers, not sellers?

We recently received an email from an eBay seller who feels that the site is unfair to sellers since it does not offer a mutual forum for both the eBay buyer and seller. Here is an excerpt from our response. We think it does a good job of summarizing our position and the guiding philosophy behind gumshoo.com:

There are several Web sites available to sellers that, for a fee, will help weed out potentially bad buyers. gumshoo.com was created to offer buyers a similar resource (for free). By design, gumshoo.com is a site for eBay buyers. We've made this choice because it allows us to offer our users unbiased information. While it is true that sellers sometimes receive negative feedback through no fault of their own and that sellers can also be the victim of scams perpetrated by buyers, it is also true that transactions in which sellers have a low feedback score, a negative feedback trend, high shipping costs, or other risk factors, are more likely to result in an unsatisfied buyer and, occasionally, outright fraud.

We feel that the mutual forum you describe is already available on eBay. In fact, all of our alerts encourage buyers to use eBay's 'Ask the seller a question' feature before bidding. This gives sellers the opportunity to explain their position, while it protects buyers from entering into transactions before they are fully aware of the risks (or lack thereof).
