The internet ruins everything. Especially well intentioned, but poorly thought our marketing campaigns. Like this latest gem from Walkers - #walkerswave.

The concept's gloriously simple - tweet us a photo and our bot will add it to a video for your chance to win a competition prize. It's audience engagement and video content in one simple package. 

The problem comes when no one checks the images which are being shared. Walkers' creative team probably imagined headshots of fans in football journeys. What they've got is Rolf Harris, Fred West and everyone's favourite dictator, Stalin.

The moral for the comms industry is a simple one. We're not going to be replaced by bots anytime soon. But hey, at least #walkerswave trended.
