If you’ve tried to buy online concert tickets in the last few years, you’re probably all too familiar with seeing an “unavailable” message just minutes after the on-sale begins. It’s the unscrupulous scalpers who buy up all the seats, then flip them on the secondary sites for a much higher price. To combat the problem on their 40-date “Public Service Announcement” reunion tour, Rage Against The Machine has a plan. According to the band’s official website, “We are doing everything we can to protect 90% of the RATM tickets from scalpers and then WE are holding in reserve 10% of the seating (random seats throughout each venue) to sell at a higher ticket price (but low enough to undercut the scalpers).”
