Facebook is the worst social networking site for internet trolling, and bullying is now more prevalent online than anywhere else, a study has suggested. Some 87% of teenagers who reported cyber abuse said they were targeted on Mark Zuckerberg’s site, while around one fifth of youngsters were picked on by Twitter trolls, the report showed. Those most frequently victimised were 19-year-old boys. According to the report, 49% of those targeted by bullies were victimised off-line, while 65% of teenagers were subjected to abuse in cyberspace. Only 37% of those who had experienced trolling ever reported it to the social network where it took place, the report found.
A basic study from PC World would appear to suggest that Twitter’s almost 1 percent clickthrough rate is double the rate of AdWords, and far and away the best available. Ads are surprisingly cheap. It’s difficult to target your ads on Twitter, but they still appear effective despite this limitation. Perhaps that’s because promoted tweets are virtually impossible for users to ignore.Think about your target market. It’s an old adage that “Twitter is for business” and “Facebook is for fun.” The experimental results bore this out, so think carefully about what social networks your potential customers are likely to be using before charging ahead.
About 50% of all junk mail on the net emerges from just 20 internet service providers (ISPs), a study has found. The survey of more than 42,000 ISPs tried to map the net’s “bad neighbourhoods” to help pinpoint sources of malicious mail. The survey by Dutch researchers found that, in many cases, ISPs specialise in particular threats such as spam and phishing. Methods to thwart attacks and predict targets also emerged from the study.
Finally, Al-Qaeda lacks the technical expertise to sabotage Britain’s national power and water systems, a cyber-security expert has told a committee of MPs. Asked why a cyber-attack had never been launched on such assets, Thomas Rid said: “Al-Qaeda are too stupid and China doesn’t want to do it.” China denies state-backed hacking and says it is, rather, a victim of it. Dr Rid, a reader in war studies at King’s College, London, was briefing the Public Accounts Committee. He said Britain’s critical infrastructure was vulnerable to disruption at sites where industrial control systems were linked to the internet.
