What is wrong with people these days !!!?

I helped so many people by answering them in "Homework Help" Section, some of the problems I solved were so lengthy that it took 30 min to write them, I knew no1 else is going to answer them, and I use to post my arcade links in Signature. Is it wrong to tell people about my site in return of the right answer. Some good for nothing guy reported me for no reason :( and I lost all of my posts and points. Now that I have appealed to yahoo they accepted and reposted my answers but I lost all of my points.

I just lost all of my enthu to help people and not going to do it anymore. It's not because I lost points, it's because people reported me of helping them... Anyways thanks to whoever reported me :|
