Answer:
Katie is a moderator for Brainly, they are taking down correct answers for absolutely no reason and is abusing the mod powers that they have been given. This exact same situation has happened with TheBubble, another moderator as well. For all I know, Brainly isn't exactly solving this dilemma either, because they couldn't care less if our answers got removed. This has been going on for a few years and since nobody knows how to get rid of it, the best thing to do is ignore all the warnings.
