You have raised a serious point that needs to be addressed. I've been to some Steemit etiquette platform where flagging was elaborately discussed and I think we all owe it to ourselves to blog about it and get stakeholders educated on its use. Some powerful jealous people can flag you down out of envy and gets away. The end is a bad business for everyone. I think 👇 vote is better or disagree button. Or options should be attached to ⛳ so you get to choose why you wanted to flag a post and it takes effect after some hours of investigation is concluded. It sounds clumsy but honestly the effect would be ugly if not addressed promptly
