How come people think that I'm an idiot for making videos for tiktok and youtube to raise awareness?

So I've decided to make some more tiktok videos and youtube videos and expose some cyber bullies, stalkers and trolls. This has been a huge problem on this site and these three people harasses people and they have done this to one user years ago. I don't get what is wrong with people and why they have such a vendetta against me that they would all of this stuff to me. My intent on making these videos is to raise awareness of cyber harassment and cyber bullying as I don't want others to go through what I went through. My friends think that I'm an idiot for making these videos. They also think that I'm a pedophile too because I also posted another video on my youtube account of some hot 16 year old tiktoker dancing. I wanna go after the people who've done me wrong as I'm sick and tired of being treated like a dog who gets beat. I want to get others to feel and know who it is to get beaten to the pulp. How come people have a problem with me making these videos to raise awareness ???
