I've just noticed that this is still happening:
Charity Auctions - YDC (Your Donation Counts) Items for Sale on eBid
uk.ebid.netBuy piece,shaped items at best prices. Signup with eBid to start buying and selling jigsaw items online

When posting a link to Facebook it's picking up default keywords and these seem to consist of jigsaw stuff. An odd choice. Surely a better more neutral set of keywords can be set to show in these circs? I remember checking the page code out years ago when this was first reported! Something less specific, please?
