If you say they are scams, why would you include affiliate links to all three? Is that not considered a bit disshonest? If you support them include affiliate links, if you don't, DON'T! It doesn't reflect well on you.
I agree these too good to be true sites are likely going to fall over at some point.
My one thought though is that if they make just 2% a day on average from trading, and give on average 1% that is technically possible. I have seen people with trading bots make 5-10% on a lot of days.
