Policymakers need to find ways to encourage recipients of scam invitations to report them, according to a new consumer fraud report.The Australian Consumer Fraud Taskforce said 98 per cent of survey respondents reported having received at least one fraudulent invitation in the previous 12 months, usually by email. The survey was conducted in 2014 and the results released this week.Seventy-five per cent said they notified someone of attempted scams but most of those reports were to family members. People said they didn't report to external organisations because they didn't know who to contact and they felt that nothing would be done about it.The ACFT survey shows that six per cent of Australians sent money in response to a request from a fraudster and three per cent sent personal details that resulted in financial loss.The most common invitations were from people pretending to be from a computer support centre wanting to fix the message recipient's computer. Lottery and other prize notifications and phishing schemes were the other common scams.However, dating scams had the highest conversion rates, where an invitation would lead to recipients sending money, and resulted in the biggest losses.The age category that reported the highest percentage of victimisation was the over-60s.The report said it was important for people to report scams to the Australian Competition and Consumer Commission's Scamwatch service and to consumer protection agencies."Even if a person is not a victim of a fraudulent invitation they should report the type of invitation and how it was received. This is important as it allows agencies to improve their knowledge and understanding of the types of frauds that are affecting the public," it said.
