Well, on the Internet you learn pretty fast not to pay too much attention to these things / negative feedback. The online world is full of trolls, and even worse. Some people even come from a criminal background; they don't care if they hurt your feelings (some of the stuff I have seen...). In fact, they will try to upset you and shock you as much as they can. If you are getting results with your online projects, then that is what matters. If not, try to find out why. But don't take haters and trolls seriously.
