Illegal UK rave crews using custom apps to avoid the police

Modern technology can be used to put on big unlicensed raves that have an old-school mentality - Mix Mag argues in their article about illegal rave crews in the UK setting up parties under the noses of the police. London-based party crew "SGL" was formed in November last year, and they have already organised three raves via a specially designed smartphone app. It transmits the party location to ravers in a way that can’t be monitored by police, and once there are around 200 people in the building then it’s much harder for the police to shut the party down, so they release the location over social media without worrying too much.
