It is rare that someone would report a post for “no reason”. They absolutely have a reason and while you may not agree with it, that doesn’t mean they are abusing the system.
Again, abuse would be if someone used multiple characters or accounts to report a single post. It might be considered abusing the reporting system if someone were using a category like “Real Life Threat” when reporting Trolling or Harassment. However, simply reporting a post, isn’t abuse.
