Fanatics share handwritten notes swearing allegiance to terror group… but accidentally reveal their locations
Online boffins were able to out the jihadi sympathisers by working out where the photographs were taken
ISIS fanatics in Europe have been outed after posting photos pledging their allegiance to the caliphate on social media.
The extremist group had urged it's followers across the continent to tweet their support for the murderous regime by posting hand written notes on the site.
But the Twitter happy jihadis have risked being identified after a team of online journalists managed to geolocate many of their tweets, sometimes down to the exact block of flats it was tweeted from.
Investigators from the website Bellingcat have managed to track down several of the "ISIS fanboys" by crowd sourcing the location of the tweet using information gathered from the photos.
The terrorist state had urged handwritten notes to be posted ahead of a speech from their spokesman Abu Mohammed al-Adnani on Saturday.
One sympathiser was tracked down to London after posting a handwritten note proclaiming his support for the caliphate.
The photo also revealed a London Underground sign and a distinctive red double-decker bus allowing internet boffins to pinpoint his or her location.
Twitter user @mamzbondok was able to use the clues unwittingly provided by the wannabe jihadi to track down the location the tweet was sent from to Bruce Grove station in North London.
The user tweeted the location to Bellingcat founder Eliot Higgins who retweeted it to his followers.
Another ISIS supporter was tracked to Münster in Germany.
Arabic journalist Jenan Moussa tweeted the picture posted by the user writing: "ISIS supporter in shows his solidarity for while walking on the streets of the city of today"
But an online tech-wiz using the twitter name @hotzn1 was able to narrow down the location to a specific traffic junction in the German city after noticing the advertising pillars in the background of the photograph.
In Amsterdam the online hunters managed to track a jihadi sympathiser right down to the flat he sent the tweet from.
From the views in the background many tweeters suggested it had been sent from one of the Dutch city's southern suburbs owing to the greenery and wide cycle paths.
Eventually the ISIS fan was tracked to Hoofddorp, a town near Amsterdam's Schipol Airport.
But the investigators were able to narrow the search yet further by studying the photograph eventually pinpointing the block of flats from where the tweet was sent.
Eliot Higgins tweeted confirmation of the finding posting: "ISIS Fanboy number 4 geolocated in Holland, thanks to the many of you that helped"
Finally a fanatic in Paris was tracked down to the Rue Championnet after tweeting an image showing a Suzuki shop in the background.
There are only about six such shops in the French capital allowing users to find the location by some inventive use of Google Maps.
User Naenil tweeted that he had been able to locate the terrorist supporter on his second attempt at looking.
