In December 2009, a campaign was launched on Facebook by Jon and Tracy Morter which generated nationwide publicity and took the track "Killing in the Name" to the coveted Christmas Number One slot in the UK Singles Chart. The campaign was ultimately successful, and "Killing in the Name" became the number-one single in the UK for Christmas 2009.
De la Rocha also promised the band would perform a free concert in the UK sometime in 2010 to celebrate the achievement.[58] True to their word, the band announced that they will be performing a free concert at Finsbury Park, London on the 6th June 2010.
The concert, dubbed "The Rage Factor", gave away all the tickets by free photo registration to prevent touting over the weekend of the 13th and 14th of February followed by an online lottery on the 17th February. This proved to be overwhelmingly popular, with many users facing connection issues. The tickets were all allocated by 13:30 on the 17th
