Not any "5 prominent users" it must be 5 prominent a given user follows.
If the user agrees with those 5, then the user doesn't want to see it as well (it doesn't matter if it is a correct report or not).
If the user does not agree with those 5 prominent accounts, they can:
1. Report those 5 for misleading reporters (if the majority agrees then those 5 accounts won't be prominent for much longer),
2. They can unfollow those 5 (or just one of them)
3. They can follow the reported account (which then, like I said in the anti-spam explainer, removes any blocks to that user).
In general:
1. Users are free to post whatever they want.
2. Other users are free to report whatever they want.
3. Followers of those users can then agree or disagree and take action as well.
