Seeing a game disliked is just as normal as seeing it liked. Don’t take it personally, it doesn’t necessarily appeal to everyone. It’s usually a dissatisfaction that can be corrected by improving the game.
However, it is unacceptable that because of a dislike, you spam everywhere that the author of the dislike is bullying you. It is rather you who are bullying them, so we ask you to stop this type of toxic behavior, which has no place in our community.
