These redirects were still happening earlier today, from what I could tell on eBay's boards.

One possibility is that this could be a problem with eBay allowing sellers to insert swf movies from 3rd party sites, which use actionscript redirects.

It happens almost instantly, and buyers are not noticing they are taken off ebay. Literally TAKEN off eBay.

eBay is taking pages with this exploit down as soon as they become known, so I've not got to look at any directly.

Some say it is some javascript doing it, but eBay disabled javascript and encrypted js a while back - the flash has always worried me...
