If your content is merely a copy of what people can see on other platforms, what value does it bring to Hive? Why would Hive users want to reward such duplicate content?
Bad memories, yes, S****it brings bad memories to many of us who were attacked, censored, and robbed by those who run it today.

No, downvoting is not a form of censorship. Hive (unlike the other platform you mentioned here) is a decentralized, censorship-resistant platform where you can store your content for free. Nobody could stop you from doing so. Sometimes, if it's high-quality, original content, you might be rewarded.
