It's basically not possible for everything to be taught in schools, imo, it'll be absurd for a course such as 'scam' to spring up in colleges and other levels of education, reason being that there is what's called intuitive knowledge; and that's what people ought to apply in situations such as obvious scam attempts. People should learn to "be their own security" and not look to the government or any other institution to protect them, sometimes all that's needed to curb people getting scammed is if they can control their own avarice.
There must be scam awareness for scam rate to reduce, and people should be taught in practical ways using forums like Bitcointalk and real life scam examples. If not because of the awareness we have on this forum, many of us would be scammed. I still remembered a day I was using pay-to-click site to earn unprofitable amount of Bitcoin before joining this forum, there was a ad that I clicked on, the site displayed me Bitcoin mining in progress, the site mined me 0.005 BTC in less than 15 seconds, displayed to me to pay 0.002 BTC into one bitcoin address to claim the mined amount, thanks to the fact I had no money to pay at the time, I would have fallen victim. Posts on this forum really oriented, just because we are educating ourselves about scam and other related matters happening in the world. If this can be introduced in schools, this will also go a long way, not even only in college but starting from high schools. They best way to prevent scam is not about government depriving people of their privacy, it is about teaching people how to avoid it with practical examples, and schools are the best means for this in away those taught in school can also educate people at home and others.
wasting their time by giving fake card numbers and sometimes the scammer is the one who gets hacked.
