He is a baseball legend who's been on the receiving end of lots of line drives and locker room trash talk, but nothing prepared curt schilling for the response he got when he tweeted about his 17 year old daughter and what schilling did next has some people calling him an all-star dad. Here's Gino Benny Tess. Reporter: He is a good sport when it comes to trash talking, but when it comes to his daughter he's got a different thought. He got a taste of how cruel online trolls can be when he tweeted this message to his daughter after she was accepted into the university. Congrats to gabby schilling who will pitch for the seahawks next year. And with that came a barrage of sexually explitity tweets at her. They alluded to lewd acts and rape. I grew up in a locker room, playing sports. I know what it means to say dumb stuff. Never in my life have I ever uttered half of the words that these guys were posting in the presence of a. Would. And I never will. Reporter: His daughter gabby eventually got wind of the trolling. There were so many comments, and they got worse and worse. And people were feeding off of them and they were all negative. I thought, I'm going to get in my car, drive three hours and beat the hell out of a couple guys. Then I started to think about it. Reporter: That's when schilling decided to take matters into his own hands. He took screen shots off the tweets and posted them on his blogs, redeveloping thevealing their identities to his fans and asking, is this okay at any time? One of the people named is somebody who used to work here as a ticket seller for the yankees. Not any more. Another tweeter has been suspended from school. Reporter: Twitter the problem directly, writing an internal memo, we suck at dealing with abuse and trolls on the platform, and we've sucked at it for we're going to start particulkicking these people off. Schilling is not the only one targeted. In fact, it's so commonplace that jimmy Kimmel pokes fun at it. We call it celebrities read mean tweets. Reporter: Asking celebrities to read aloud tweets about them. You were better when you wore the spandex instead of Reporter: And last month, iggy azalea became the latest to swear off Twitter. She wrote, I file the hatred and pettiness I see online at all times is making me be an angry person. She also revealed her thoughts in an interview last summer. So I kind of find it really ironic when I see 12 year Olds tweet me and being, like, you suck. We have a number one. And I'm like, you don't have a number one. Your favorite artist does, but you're 12. Writing this from your mom's computer? Reporter: Iggy can hand off her Twitter account to her managers, but for the thousands of students bullied online each day, there's often no place to hide. You are so gross. You are so pathetic it's so funny. It's like what did I even do? Reporter: Last year, "Nightline" visited with Jamie. I'm going to throw a rock at your head when you are cheerleading. You suck at it anyway, you troll. They would tell me to kill myself and cut myself. Reporter: The harassment caused her grades to plummet and made her paranoid in school. She was left wondering which one of her classmates might be an online tormenter. I could be walking next to them. It would be my best friend. She could be planning to do it the next night and I would have no clue. Reporter: They told us they pro actively scan posts and take down offensive content. We reached out for comment but have not heard back at airtime. The world the internet creates is alarmingly like what the brain of a psychopath looks like. Reporter: Paula Todd is the author of "Extreme mean", and says anonymity contributes to this type of cyber bullying. We could be living in the mind-set of a psychopath. And that means not caring about each other. Not seeing each other. Getting your laughs at the expense of somebody else or really, really hurting somebody. That's how a psychopath feels. Reporter: It took the intervention of parents and school administrators to stop the bullies. She's a different girl than the one who ran away and attempted suicide. She has a close circle of friends and is even playing a part in her high school musical, but not every teen is as lucky as Jamie. She was so derespondent and depressed that she attempted to take her life. Reporter: The attempt was two years ago after key Anna, a high school cheerleader received harassing posts on the same social media site, ask fm. They threatened her. Called her horrible names. Even told her that they would help her kill herself. Reporter: Key ahna survived the suicide attempt, Baugh brain injury left her unable to walk. If signed into law, this make cyber bullying punishable by up to six months in jail. It will help other people. Reporter: 34 states have already enacted laws. In most cases, non-engagement is the best tactic to use when confronted by these type of bullies. Parents have to look at this and realize they may not be curt schilling. And you want to be cautious. What you don't want to do is incite this to grow into something bigger. Reporter: For curt schilling, calling out the trolls who attacked his daughter is a small thing. I think people look at this situation and are a lot more careful about what they say. Nobody should be able to get away with saying things like that to a father about their daughter. Anyone. Reporter: Not unless you want the father to strike you out. So, should there be stricter laws protecting you and your children from online bullying?
