Exeter residents are being asked to help crack down on graffiti 'taggers' - with the help of Facebook.
The city council have set up a page on the social networking site, displaying some of the commonest tags, in the hope that someone who knows who's behind them will come forward.
If their information leads to a prosecution, they'll get a cash reward.
The page is available here.
