In 1973, African-American baseball legend Hank Aaron received hundreds of thousands of hate mail letters from fans, angry at him for trying to break the all-time homerun record at the time set by Babe Ruth. Aaron would eventually break Ruth's homerun record by hitting his 715th homerun on April 8th, 1974. That same year, the U.S. Postal Service confirmed that Hank Aaron set the Guinness World Record for most mail received by any private citizen in one year, receiving over 900,000 letters with a third of them being letters of hate.
