People are free to say whatever they want and deal with the consequences of what they say. This person's actions are forever on the blockchain. They can be viewed by anyone via browsers like steemd.com. Thankfully, the steemit.com interface hides content from people like this who appear unstable and needing way too much attention. If you think their content shouldn't have been flagged, you're welcome to get your own Steem Power and give a counter up vote. You could even build your own blockchain front end if you don't like how Steemit displays things. It's all open source.
