It's definitely their loss no doubt and not yours because you have done your fair part and it's up to them to take the next step, well it's possible they might have better things they make money from too
The problem is that it is not only their own loss but it is also our loss as we do not get to earn money if we do not refer people. Most of the websites always ask you to refer more and more people in order to earn a significant sum of money and if people do not take you seriously, then it would be your loss.
