The best defense is to slow down, read carefully, and use common sense. If something feels too good to be true, it usually is. It's really unfortunate that so many of these schemes exist, but it just takes a little bit of caution and a willingness to do some research on your own.
If these tips are for real, we're all rich. It's the same as finding a trading signal that people claim that they're winning their trades. These people need to realize that if life is too easy then no one is ever going to be poor again and we're all in the same status of life that we're just enjoying the money that we're having. But no, it's not like what they're thinking with these signals and tips that they think will make their lives easy. Maybe at first when they get some accuracy but in the long run, they're not going to be the same as-is.
Although the idea is always to help and give good advice to move forward, it is not bad, what they say is very true, when I go to make a bet or play at the casino I try to bet what I can and not more than I should because how do I recover the money later ? The last time I tried to recover money by making bets I lost more than I had lost before, so sometimes desperation does not help and much less in trusting that with other future plays we will recover it, sometimes desperation leads to that and to see something that is very bad, like the schemes that everyone knows and are fraudulent.
It is better to bet little and win little, and not lose a lot with our methods.
