It’s rare for a company to invite people to splash a problem across social media. Domino’s has even created a hashtag.

The company that made its name delivering pizzas in 30 minutes or less now wants Instagrammers to post pictures of any stores still using the Domino’s Pizza logo and signage.

“We’ve changed from Domino’s Pizza to simply Domino’s because we’re more than pizza,” the company says.

Logo Informants from Domino's website

Anyone who uploads to Instagram a picture of a store displaying the old Domino’s Pizza logo and signage becomes eligible to win a prize. The picture needs to be tagged with #LOGOINFORMANTS and #SWEEPS.

The grand prizes for this social media shaming, curiously enough, are free pizza for a year.
