When celebrities behave oddly online people notice. To help eBay communicate one of the biggest changes to it's platform in decades, we partnered with Australia's most famously explosive twins - The Veronicas - and staged a very public act of sisterly revenge. Conducted entirely through eBay listings. Because now that it’s free to sell on eBay, there's absolutely no reason NOT to sell things on eBay, even if those things belong to your famous twin sister and bandmate.

Lisa listed Jess’ prized items on eBay without Jess knowing. Jess retaliated by listing Lisa’s things.

We then seeded the listings on Reddit and let internet slueths and die hard fans take over.

The Veronicas explained what they were up to in a series of entertaining films.

The fans lit up the comments section.

Resulting in national press coverage of The Veronicas’ antics and eBay’s new free to sell offering.

All of The Veronicas listings were snapped up by fans on launch day.
