Robbie Savage has described how he fell out of love with Twitter after he was subjected to vile abuse following the death of his father.
The former Welsh international claims that he has become "scared" of the consequences of posting the wrong thing on social media.
Savage believes trolls cannot be stopped and unlike abuse suffered at a match... it can be endless.
He told the Daily Telegraph at the Telegraph Business of Sport Conference, Savage said: “When your father passes away and, instantly, people say, ‘Has he rotted yet?’, the day he died, it’s just ridiculous.
“I don’t really get involved any more. I used to love it and tweet things inside my house or in my garden but now I don’t bother.
“The trolls, it’s a nightmare. But how can you stop them? I don’t think you can.
“The 30,000 fans calling me a name on a football pitch doesn’t bother me at all. But the trolls, it’s just incredible. They know no bounds.”
The former Wales midfielder described how he saved one of his trolls from the sack, a Manchester United-supporting company director who abused him when drunk.
He said: “He left his e-mail address on my Twitter, so I retweeted his nasty comments to me and obviously a few of my followers must have e-mailed his company and he was going to get the sack.
“He then direct messaged me, because I followed him, and was begging me to save his job for him.
“The next day, I had to ring his boss and save him his job.”
