What if I want to share something without adding noise or my redundant commentary? What if I want to invite conversation by introducing content to discuss first, without my opinion which I will share in reply to comment(s)?

No, it is far from "no effort" posting. If waving reward from such posts is a best practice then I shall do that for my future posts, provided that you remove me from blocklist. Instead of blocklisting, you could hint that suggestion, or say that continuing such practice could lead to blacklisting, couldn't you, instead of aggressively striking me right away. Note how you reprimanded one post of mine regardless of my original commentary. Do you wish to dispute size and quality of added content, to qualify for reward and immunity from your misconduct?

No, it could NOT be "considered cross-posting spam littering the chain". Spam is characterised by excessive and/or redundant posting. One unique post per day in the appropriate community dedicated to exactly such content can hardly be considered "spam", let alone "littering the chain".

What actually is "littering the chain" is "original" meaningless noise in posts that tell readers nothing worth knowing yet rip massive rewards from upvoting cartels -- a something that can be found on Hive in abundance.

Originality of content is overrated. Original content can be spam, rudeness, vulgarity, hate, lies, slander, disinformation, sensationalism, fear-mongering, etc. Original content can be meaningless noise. One might even question whether truly original content even exist, as we are all influenced by culture, hence to some extent almost all "original" content is a derivative. Suppose I am to post selfie, or photo of something that I ate for breakfast, or narcissistic post "look, I'm waiting for a train" (like if everyone must know), or boring photos of food or cats -- is that "original" if millions of people do the same, and were doing the same since a while ago? What if non-original content enrich Hive community more than my blabbering?

Discovery and sharing of worthy content is equally important or even more important than trying to produce content of your own. At least I hope you'd agree that good balance is to be found.
