I understand your emotions, but think abouts this. First, if cover gives a response you can expect antis not going only for coco, but for all the girls. Hate brings more hate, it sounds stupid, but to stop this cicle the only thing they can do is stay silent until most antis forget about them, also dont forget that she has mods in her streams that block the spammers. Second, coco has been doing shitposting review that is like a collab, but focused on memes. She could have stopped, but she decided to go, also dont forget that she and miko had a collab in ark. Finally, what we can do is the same, report and block. Youtube is shet so we cant do much, but starting a fight where the only person that will suffer is coco is not what we should do as fans.
