I don't for one moment think it isn't possible for Twitter to have some software that would reject a whole lot of tweets, but they'd probably end up blocking a lot of innocent tweets in the process..
And on the back of this, here is a story where two people are now serving prison terms for sitting back in their chairs, abusing others on Twitter and thinking nothing more of it. Now, they've only got 8 weeks, but I bet they're sorry as hell right now. No doubt they thought nothing of what they did, but now they know there are consequences. And imagine that conversation they'll have in prison: "What are you in for"?... "Oh, I made threats and abusive remarks on Twitter".
There are also lawyers specialising in this already, also as a Forum owner or other 2nd level publisher you can also be as responsible as the person writing. UK for example acknowledges this some other countries may not.
Yes. Thats the pair that I mentioned in Post# 8 There seems to be some prosecutions going on. I like this one though.....LOL...... English boxer Curtis Woodhouse turns up on the doorstep of his Twitter troll "When the light-welterweight and former Birmingham City and Hull City footballer received abusive tweets about his defeat to Shane Singleton, he took matters into his own hands" http://www.theguardian.com/sport/2013/mar/12/english-boxer-curtis-woodhouse-twitter-troll "When Curtis Woodhouse lost his English light-welterweight title on points to Shane Singleton on Friday night , he was branded a "disgrace" on the social networking site by 'Jimmyob88', who has reportedly been abusing Woodhouse on Twitter for months. The boxer was so enraged with the tweets that he offered his followers a £1,000 reward if they could help him locate the culprit. Woodhouse's growing number of Twitter followers chipped in and managed to track down his troll. Woodhouse set off to find his troll, tweeting a photograph of the street on which Jimmyob88 lived. "Right Jimbob, I'm here," he wrote, adding: "Someone tell me what number he lives at or do I have to knock on every door #itsshowtime." Realising the error of his ways, Jimmyob88 replied: "I am sorry it's getting a bit out of hand. I am in the wrong. I accept that." A triumphant Woodhouse went home, joking that he could have saved himself some petrol money by blocking his cowardly abuser."
Heres another good one.... Danny Dyer responds to homophobic Twitter abuse: 'Here's a little message for you' http://www.heatworld.com/Celeb-News...Twitter-abuse-Heres-a-little-message-for-you/
James Blunt is the king of Twitter as far as I am concerned. Nobody trolls him and wins... But then I guess a stint in the British Armed forces more than prepared him for a few Twitter trolls!
