Driffield - British boxer Curtis Woodhouse got so mad, he decided to track his Twitter tormentor down.
Woodhouse, a former footballer who played with Hull, set off to find the Twitter user who had been abusing him via the social media networking site following his English light-welterweight title fight loss on Friday.
Woodhouse tweeted: "I'll give (pounds) 1 000 to anybody who provides me with an address and picture of this man. Knock, knock."
The boxer apparently even showed up on the person's street in northern England, tweeting: "He never came out to play so I'm going back home. It was maybe a bit daft what I did today but sometimes enough is enough."
Former heavyweight champion Lennox Lewis applauded Woodhouse for his antics, tweeting: "Ha! I LOVE this story about (at)woodhousecurtis paying a visit to a (hashtag)keyboardwarrior on Twitter."
