While flagging is, imho, shown to be abusive, particularly as your experience demonstrates, and counterproductive to Steemit becoming more widely adopted by people, that, for example, agree with those posts you made that were so flagged, at least the posts themselves weren't simply deleted.

Your words were still communicated, although you clearly were demotivated from speaking. Such speech as you did undertake remains available on the blockchain, and, afaik, will remain so regardless of any intent to censor you.

You are clearly correct that Steemit is the least censorable medium presently available, afaik. It is fortunate that those that would censor you aren't able to assume the power inherent in systems amenable to centralization.
