The road rap scene centres around mixtape releases and YouTube videos with some of the genres more popular acts getting mainstream recognition. The genre has been criticised for the relentless nihilism and violence in its lyrics as well as its links to gangs and gun crime with many rappers serving prison sentences. In keeping with grime, road rap has suffered from preemptive policing with Giggs claiming that the Metropolitan Police have set out to deny him the opportunity to make a living from music having banned him from touring. In 2011, Stigs was served the first ever gang injunction that banned him from rapping about anything that may encourage violence.
