I think the biggest problem people have with LS or any other similar service is the expectation of the average punter is totally unrealistic.
Basically they want a trading account to act like a salary/income, keep pumping out the money month after month like clockwork. So if a strategy is expected to make 60% a year they expect 5% a month (no compounding) every month. And when it doesn't happen, say it goes 6 months losing 3% a month it's automatically total crap.
Trend followers can go for months not making a penny and then bam, catch a few good ones and all the money that's lost is made back and a profit leading to the 60% return over the year.
This is why in my opinion the majority aren't suited to the financial markets, they seem to think it's their right to only have gains and get all upset when losses occur, even if they are short term.
Look how many people are complaining about the value of their pension for example? Well, if you don't like potential losses why have you been investing in securities that can go lower? Instead they should have kept all their cash on deposit but then they'd only complain they were earning 4% a year when perhaps the stockmarket went up 20%
