RE: Steemit Content Analysis
I have a feeling the person who might best be able to answer your question about blockchain data and queries is steemchiller
I already received a reply from @moecki and he described to me what the difficulties are and what are the options for obtaining such information.
Does the Steemit team have such a person(s)?
When it comes to the Steemit team, it's hard for me to comment because of the veil of secrecy that surrounds it. However, since I signed up to Steemit, I have never seen any press releases or just news about Steem. Therefore, I can assume that there is no public relations team.
Interesting coincidence, but I thought the same thing as you and even did a little research. If you follow the link, you will see the prices for publishing articles and press releases in some mass media. I don't even know if it will pay off.
