With the increase in bullying cases worldwide, some tweeters republished a video clip of American boxing champion Donettai Wilder as he retaliated against his bullies and his daughter.

The incident dates back to 2014 when a boxing freak blogger named Charlie Zelenov sent a challenging message to Wilder over the phone, in which he addressed some racist insults and insults to him and his sick daughter.

The then heavyweight world champion did not miss the opportunity and responded to the challenge, but rather traveled specifically to Los Angeles to face the bully immersed in a boxing arena in a gym.

Zelenov - who claims to be a boxer even though he did not have any official fight in his life - tried to take the shot to gain his reputation and escape from the ring, but Wilder caught up with him and punched him with the punches that brought him to the ground more than once.

Wilder warned Zelenov as he beat him against repeating it, telling him "Don't call me the Negro again," and threatened him if he chased his daughter again.

Zelenov infuriated everyone by insisting that videos be posted on his official Instagram account, while some people were violently beaten, in a miserable attempt to prove he was a professional boxer, as he claims.
