18+ asian girl :: Is the steem is totally moderated?

Good evening everybody. As you know, I like to post some nice pictures here. Some one like some one not. It's ok.
But how do you think, the possibility to search and find what you wants is the main property isn't it?
Because today I can't find the #sex tag. And some other tags too. What does it mean?
Is the steemit is totally moderated "blockchain"?
BTW, have you eat a rice already? )
