Thanks for the thorough reply and tips!
I can't say I agree with everything though. Yes, you are right that there are laws against plagiarism and for copyright, however the Steemit website is not responsible for any of the content, as it is all stored on the public STEEM blockchain. Steemit is merely a transmitter, in the same way that your e-mail client is not responsible for the contents of your e-mails, and like how your ISP is not responsible for the content on the WWW.
If there are any copyright claims and lawsuits, these ought to be filed against those people who violated the copyright to begin with on a peer-to-peer basis?
Secondly, many of the above mentioned cases do not involve any copy/pasting at all. A fair deal of flags have been handed out to people for posting referral links, ranging from Genesis mining to Bitconnect, under the guise of fighting scams. Ironically, Steemit too offers money for signing up, and is often called a scam or ponzi scheme, so it's rather hypocritical to censor other projects without proof. Pointing out that somebody can pick up free tokens somewhere should be allowed - I personally searched on Steemit at one point for new places where I could get some more free crypto, I even compiled it all into a list and posted it on my feed and a bunch of people found it really handy. There are many people like me. Why are we being disallowed to even talk about these projects, or share links with eachother?
Another group of people are targetted because they make the move from other social media platforms. They are now sometimes forced to do a sort of digital Know-Your-Customer procedure, often being required to post a photograph (or even a video, I saw people call out for !!) and sacrificing RL privacy in the process. Personally I am of the belief that one is innocent until proven guilty, and the burden of proof lies with the accuser and not the accused.
