Ebay, in an attempt to reduce fraud, enacted suspensions based on what appears to be a questionable 2% across the board unsatisfaction rate - some mathmatical formula performed via shell script most likely - catching many good, but low volume sellers in the net. All over the boards and seller sites, sellers with high numbers and ratings over 99.5 have been suspended or limited.
As usual, what were they thinking?
If a seller has a huge number of feedbacks, they could ambush a competitor quickly and easily, and they have no recourse.
Vendetta suspensions are also highly probably with the new system. All anyone would need to shut down a small time seller they didn't like was to numerous IDs, then bid on a seller's auctions, win them, leave negs and *poof* they are history and the 'buyers' would not even need to worry about pay.

In the meantime, thousands of eBay sellers are very nervous, and openng all the spoof emails taking advantage of the new policy.

And eBay could possibly say their earnings - if down- are because they have been 'culling' the fraud from their site, instead of the normal lull in summer listings or the recent problems with Google's listings.
