A 4chan user appealed to members of the online community to vote for Charles, and with the help of Reddit users and spambots, the "fat old guy" won.
"My creepy 39-year-old friend named Charles would like to crush all those girls' dreams (and then sniff Taylor Swift's hair cos he's into that) by winning this instead… Help him crush the dreams of these girls and give him a chance to make a complete ass of himself by blatantly just sniffing her hair with the cameras rolling."
Upin finding out that Charles had won with the help of Internet trolls, KISS FM canceled the contest.
"Disappointingly, we have determined that the integrity of the "Taylor Swift's Biggest Fan" contest has been compromised. In accordance with our contest rules, effective immediately, the contest has been terminated."
As a contestant, however, Charles appeared more innocent, saying on his profile, "I'm a 39-year-old man and I love Taylor so much and don't care that both adults and children mock me for it."
This isn't the first time a Taylor Swift competition has been hijacked by trolls. Last year, 4chan users made a school for the deaf win a competition offering a chance to have Swift come and perform for students.
