I find myself conflicted about this. Free speech is a valuable thing and is much more limited in places beyond the US and Europe. People can be locked up or even killed for criticising leaders or religion. I know there are some on Hive who see it as an outlet for those who get banned elsewhere and they do tend to be on the political right wing. I can see why any commercial platform would not want them, but then they tolerated Trump for years and allowed him to build a massive following. Twitter have shut down thousands of ISIS accounts. Should they be encouraged to use Hive too?

The front ends do have blacklists as they have to conform to local laws. I know there was someone sharing pirated movies on Steemit. Anyone can set up a site to show the content and decide what they want to block, or not. They could ignore flags. They could even set up their own blockchain with the same software.

It's going to be interesting to see what happens next, but I really hope that Hive can still be a place for the rest of us. I know some people have been put off that extreme content is allowed.
