Deontay Wilder is a household name in the world of boxing and in the world of sport itself.
However, you could comfortably say this wasn't the case five years ago. Despite having a professional record of 30-0 by 2014, many outside of USA wouldn't have even heard of the Bronze Bomber.
In fact, even some Americans wouldn't have heard of him.
Up until recently, Wilder's boxing resume was a bit of a 'who's who' with no real big names springing to attention. Although that has changed in recent times with his fights against Tyson Fury, Luis Ortiz and Dominic Breazeale, but the 33-year-old was an unknown quantity back in 2014.
Having said that, he was still a target of online abuse and 'trolling', and none more so than a guy named Charlie Zelenoff.

Zelenoff liked to make out he was an impressive boxer, and was once filmed beating someone up outside of the ring and quite frankly bullying his 'opponent'.
However, it's safe to say he chose to pick on the wrong guy in Deontay Wilder.
After sending the pro boxer racial abuse and sending threatening messages regarding the boxer's own daughter, Wilder decided to pay Zelenoff a little visit in his gym.
Not only did he pay him a little visit, he absolutely destroyed him and made him pay for his online abuse.
The video that went viral a few years ago did the rounds once again earlier this year when talkSPORT reporter Michael Benson tweeted it out to his many followers.
In the clip, you can quite easily hear Wilder shouting: "Don't you ever call me a n****r again.
"Don't you ever say you're going to tape my daughter."
Zelenoff himself tried to get involved and was seen throwing a few attempts at Wilder, but clearly, he was unsuccessful.
A lesson to everyone, if they didn't need it already, don't be a keyboard warrior, as one day, you may get what's coming to you.News Now - Sport News
