Getting rid of this junk is a job. A much bigger challenge from my point of view is to bring good content to the platform. A start from 0 is hard and uncomfortable, considering all the rules and pitfalls. I didn't think it would be that difficult to win someone for the Steem Blockchain. So far I have only succeeded with one person and this person is inactive so far. A very good friend accompanies my experiment here on Steem and finds out that not much is going on here. If the Steem Blockchain wants to survive, then it must succeed in generating a noticeable added value for the user. Only through high-quality content will we be able to attract the attention of other platforms to the Steem. Although I have also invested some money in steem power, I have not yet been able to make a financial profit. I have written 400 posts and never received a Delgation from Steem power. Nevertheless, many users are happy about my contributions and show me that with their vote, even if it seems worthless. Even if the whales can't do much with butterflies and macro photography, I remain true to myself and continue on my way as before. With Steem I don't have to earn my bread rolls but have fun and remain curious. As you already mentioned, this is an experiment. I am there and will experience where the train goes.
