Nothing public with a hard outline. Are you looking to invest advertisement money into a platform? We really don't tend to be a place that has a lot of rules. A standard advertisement relationship simply does not fit their current business model. They don’t want be the next YouTube or Twitter where companies pull advertisement money out and force that company to “fall back in line” to get the money. People value free speech more than anything else here. If you are expecting “YouTube level of advertisement friendly” then this place is far from it, and its best to look elsewhere. People in general do not want ads running alongside/on their blogs. Besides that an old business model that will die off from better ad blocking measures.
If you’re looking for rules and regulations for paying a blogger here to advertise then I do not believe there is anything in that regards. We are more of a “does the blockchain allow it” place. Therefore, if you choose to pay a blogger here 20,000 STEEM to promote your new line of shoes then by all means go for it. We are not set up with a marketplace that handles the legal agreements for that. That would have to be something creating by a member of the community who choose to run it and gain trust worth reputation. A major project like that would require the backing of a few witness who put their trust and name behind such an endeavor. For anyone to trust it.
RE: ATTENTION: there is no income for steem, so the project value is going to zero. I invite all steem fans to tell me how steem earns money itself.
