Metallica fans have taken to Twitter to express their outrage after the pre-sale for the band’s upcoming “S&M2” show with the San Francisco Symphony ended within seconds due to bots grabbing all the available tickets. Members of Metallica’s fan club were supposed to be given the opportunity to buy tickets a few days early, but it was reported that tickets began showing up instantly at StubHub before fans had a chance to view their pre-sale opportunity. Fans reported signing in at exactly 9:00 a.m. PT and being unable to purchase a single ticket, while tickets went on sale at StubHub via resellers at prices ranging from $300 to $16,000 for one ticket.
