Seems everyone knows someone who’s been robbed in Barcelona. And sadly, the city we love to visit shows no signs of improvement on the thievery front.

But one man’s made it his mission, as they say, to warn visitors (in 20 languages!), to aggregate information on local theft, and to shame city officials into taking action. “Rob Daly” has created the activist website RobbedInBarcelona.com, with the mission statement: “We intend to use the power of the web, and the English language, to internationally embarrass Barcelona’s local authorities into taking action on pickpocketing. Visitors to Barcelona should have a look before their travels.

Many, though, will see the site only after it’s too late. That’s because Robbed In Barcelona has made it possible for victims of theft to notify the city’s mayor by filling out an online form. The site administrator will then forward the complaint at no charge, and send back the mayor’s reply, if there is one. Imagine the impact if every day hundreds of victims send complaints to the mayor’s office! (Imagine the work for the unpaid site administer!)

Obviously, it’s better to avoid that necessity by being travel-savvy before setting off. Browse Robbed In Barcelona to see local newspaper articles and tv news pieces translated into English, to read victims’ experiences, to bone up on the local thieves’ latest dirty tricks, and, if nothing else, to get a sense of just how serious the situation has become. There are also occasional guest posts—including one by yours truly on the infamous Ronaldinho football method of pickpocketing.

Robbed in Barcelona is doing much to make city officials aware that Barcelona’s residents and visitors are sick and tired of the current level of crime and want something done about it. Besides pressuring the mayor’s office with victims’ reports, and besides posting multilingual warnings to potential visitors, it singlehandedly assumed the role of chief forewarner to delegates attending last week’s Mobile World Congress, a huge convention that Barcelona’s crime rate threatens to chase away.
