Another way of seeing it is "nobody is".
I can decide what brings value to ME. But I shouldn't judge on behalf of THE COMMUNITY, nobody placed any power-of-attorney in me ! I can only talk for myself. You can only talk for yourself, you cannot suddenly decide that, because YOUR PERSONAL JUDGEMENT says that it doesn't bring value to you then it automatically means that it doesn't bring value to THE COMMUNITY.
Actually, I'm not sure you even realize the enormity of what you've written ... We get to vote FOR OURSELVES. Your vote indicate what is valuable (or not) FOR YOU! You have absolutely NO RIGHT to imagine that you speak on behalf of THE COMMUNITY.
YOU and THE COMMUNITY are distinct entities. THE COMMUNITY as a whole cannot vote. What is valuable for it results from the aggregate of individual values. If you flag something that many people upvoted it means you are challenging the judgement of the people who upvoted, you are defying them, by annihilating the effect of their vote you want to deny them the right to express their appreciation. It is extremely destructive.
In case the value comes from bots then it means you are defying and challenging the current steemit system. You can do that indeed, I too believe the current HF19 could do with some tweaking, but I think downvoting is the wrong approach. We should instead plead with whoever can do something about it to change the system.
If you want Steem to be successful then you (speaking generally, not just you personally) need to be assessing what in your opinion adds value to the community (especially the community of investors who have entrusted their capital to STEEM/SP) and what does not. And then expressing that with voting. Because otherwise there is no mechanism to ensure the investors' money being spent on rewards is actually delivering value, and instead those who value their own personal enrichment will prevail. Investors will then abandon it and it will die.
There is no 'free money' here. It all comes from investors who buy in. Unless limits are put on those who want to take that money and put it straight into their pockets, investors will turn off the lights and the party will be over.
You are wrong.
Thank you for taking the time to debate. I'm preparing a more elaborate answer that I'll publish as a standalone post because I am convinced the debate is central to the future of steem (the blockchain system)
