I’ll be adding the EBAY Blog Monster to NSS 2 (black hat side) in a few hours.  No huge fanfare or anything but it takes a keyword and does it’s thing.

You give it your wordpress blog xmlrpc url.

You give it your Category ID number (it’s in the admin area - might have to hover over the category names to see the id number in the url depending on your WP version).

You give it a keyword.

It posts 200 ebay items to your blog.
It does need php5+ to run.
