WATCH: Keys addresses cyber bullying

Madison Keys is on a mission against social media abuse.

Following a first-round defeat in Charleston to Shelby Rogers, the 22-year-old took to Twitter, sharing some of the abusive messages that she had received.

Keys said her ability to take a stand is tied to improved personal confidence.

"I think part of that has been being more vocal about certain things on Twitter. I just think if we are all quiet and we don't talk about things, then nothing is going to get better," she said, speaking to local press ahead of Charleston.

In a newly released TenniStory presented by Tennis Express feature for the Tennis Channel, she talks about her struggles online, and even reads some of the tweets aloud.

Her social media activism is also tied to her work for FearlesslyGIRL, an organization that promotes social awareness among girls. She became an ambassador for the group in 2016, and has hosted summits speaking to girls about social issues such as online abuse.

Keys and other players like Nicole Gibbs, Steve Johnson, Kyle Edmund and Sam Groth are becoming increasingly vocal about the large amounts of vile messages they can receive following defeats, and even victories.

Lately, Keys has noticed that reacting to the senders and drawing attention to the problem could help reduce the amount of hate she, and other players, are receiving.

"I think actually there has been a lot [of positivity on social media]," Keys said. "And part of it is if you make the people saying then negative things be accountable for them, it makes people second guess themselves when they're going to write something nasty."
