Tips on how my band can be better? We've been harred a lot lately?

me and my band is really cool. concerts all the time. but lately weve been having some trouble. Last week at our concert, someone threw a wrench on stage. It almost hit our lead singer, Table. He was really scared and i felt bad. Then our other band memeber, Scruffy, gets harred a lot. Someone called him a d bag and poosay. And like nobody comes to our shows anymore. I hand out flyers but lately only our grandparents and 2nd cousins have been comming. We try to start mosh pits but thne people laugh and leave and pee outside. We dont appreciate the harrment. We are on the way to stardom. Our idols are the jonas brothers. We send them fan mail and videos of our concerts but they never reply. I don't want to leave the because we just ordered our new spandex pants with sequin flames. Please help what are we doing wrong
