I can relate to this post.
first came the suspensions on facebook, then youtube channel closure, and finally lost my twtter a few months back. Now I'm trying Steemit with renewed hope even though I've already stumbled on a few posts and comments hidden by negative flags, and in some cases it was flagging of opinions and not abuses. This is concerning but something that can be solved.
I think flagging should be reserved for clear cut abuses : abusive language, plagiarism, spam etc and never used to bury opinions . This needs to be stated clearly in the FAQ (currently it is not) .
Also Steemit, though based on a blockchain database, is currently still a centralized website so it can be easily targeted by governments.
Steemit needs to become a decentralized application to really be censorship-proof.
