That is no f**king proof that he actually killed himself. If people were online calling him a pedophile and harassing him for days I would delete my account too. You can't jump to conclusions like that. It helps nobody. None of this is confirmed AT ALL. Stop spreading bullshit.
And if you somehow, seriously believe this person took his own life because of being bullied on the internet which YOU PARTICIPATED IN, and your response to being confronted about making jokes on a post threatening suicide, you should be serving jail time because you a partially responsible for ending a human life.
But I still don't f**king believe you. You're just trying to get attention. If somebody killed themselves, why would you announce it on top of a meme wallpaper? Use a black screen or some form of respect for the love of G-d
