why do you think Steem is the answer here? and more importantly why do you even think Steem is decentralized?
you are talking about the "social media platform" aren't you? in which case Steem is not even a social media platform it is centralized website more like reddit.
you see the token called "steem" may be decentralized and it is obviously based on the blockchain technology but the "platform" called "steem" (which you are looking for as an alternative to centralized Facebook) is neither decentralized nor uses blockchain technology. it is simply a website like Facebook, Reddit,... where you have to first sign up on and whatever posts you make are stored in their centralized database (note that this database is not blockchain!) and they control your account and what you post so it is not decentralized either.
a decentralized social media platform is when you download a wallet, own private keys, make transactions (posts) and broadcast them to the network (other peers) on the P2P network instead of sending it to a server.
Thanks for your sharing. Almost people here are thinking about Steem. My Steem account banned, that means they can control everything. So Steem isn't decentralized. I don't having experience in tech, is that right?
well as far as the platform goes (which is the only reason why they created this coin in first place) it is fully centralized. as you have experienced it already, they can "ban your account" which is a clear sign of centralized platform.
