It's very simple, my comment feed isn't your billboard.
If you think you have an awesome project, make me want to write about it and pitch it to me. Preferably in a way that it doesn't offend me (read not as an unrelated comment, they who want to will find ways to reach one).
If you think that my comments feed, because public, is your billboard, then don't cry foul when I disagree.
This is a problem for all start'ups, how are you going to write for my project if you don't know it ? how do I attract your attention ? I think this is why communication has been invented for. I agree that it can be very annoying, I agree that your comment feed is not my billboard.
Perfect reply.
Rather than posting those comments, find peers. Find the people who matter and who have reach. Discover them on Steem, in Steemit.chat or on Discord. Cultivate relationships with them. Build a following by following and adding value first.
Know when to pitch your project and to whom.
The returns will be much larger than some mechanism which you think is awesome (self-beneficiary) but which also takes from the pool everyone shares in. Takes in the most optimal way.
You have rep 61, surely you can think of better ways to do it. Renewable energy. Much loving for such projects can be found. But not the way you are doing it.
I do like your request for people who approve of that comment btw.
Steemians are good people, generally, but I don't run in your garden either and shout at your window that you should check out my project which aims to promote all awesome on steem (tech related).
It's not a death spiral, still lots of awesomeness can be done. We just don't need to join the greyhat/unethical brigade.
