All your edits were on others' walls. And you were removed for harassment. I am not sure Heroes Wiki has what you are seeking. It is not a forum, it is a cataloging center across media for protagonists. My advice would be to join/start a discord so you can speak with others or debate merits of media to your heart's content.
Clowns did many dangerous things to Dumbo, and they are shown to haven't got feelings, one of them said that they will kick Dumbo from 150th floor to earn money, and that elephants haven't go tfeelings, and that Dumbo will not feel pain.
Apparently that is a redirect from another page, Max Medici. Real name I presume. So it was deleted for being a double of the original, that is all. The rest you will need deliberation from a full admin for, I am just an extra hand. I suggest you wait for Magma. Though as you are new here, I suggest you do not pester him, check in no more than once a day and go to the Discord if you need immediate attention.
As I said, Johnny was intentionally put on CFD, and the description ask none besides an admin restore it, so you need to wait for deliberation for that one. ROR should be checked over, it is fine to be restored for now, but it should be deleted or kept on it's own merits, neither due to category spam or a simple request. Just check in with a full admin for those, but again, I strongly encourage you to check in, not pester. Everyone has different scheduels it is unlikely you are being ignored, and if they come on and see 20 messages in a day, they will not react well.
Max was also intentionally deleted it seems. Check with the Deleter, B1bl1kal. He deleted it due to this being before animal rights, I would disagree for his reaosning, after all slavery was once legal, Pharoah (The Bible) is still here. But I will not second-guess a full admin, if you want that page restored get B1blIkal's blessing.
What about Rhode Island Red and Henry Bear? Also, please delete Tasmanian Devil, because he became a flawed hero over the years, yes, he made some bad moves at the beginning, but he's obliviously not a villain, in fact a pure hero.
Both Rhode Island Red and Henry Bear were just info boxes, categories and three line description, too scarse to be full pages. As for Taz, keep in-mind we allow characters who act as villains in previous contexts. Vegita is still here and he is eventually reformed. Odin and Zeus are here, due to certain teling of their stories. So even if Taz has had character evolution, in those old cartoons durring his first runs, he was still the antagonists of those episodes.
Can you please delete Rudy (Ice Age) and Roger (Ice Age: Collision Course)? Rudy is nothing but normal predator and Roger is just stealing eggs, which is normal for dinosaurs. He even reformed his evil father and sister who are focing him to steal and kill Buck, ans they all helpt others to stop the meteor which was going to destroy earth. He even has a page on Heroes Wiki.
