Thank you for your advice.
We have stopped those incorrect promotion methods.
@steemscan is another of our projects that are not online yet. These two accounts temporarily have the same avatar.
Furthermore, this project was launched first,so we took the SP for this account.
I agree with @imisstheoldkanye. You start dropping links on peoples posts, and they will downvote you to oblivion. Two things that you might investigate, or think about, beyond what has already been said. You might try to connect with a few of the Higher Ups in the steem community or at least someone who knows the ecosystem, otherwise, you will be lost. Unless you throw an ungodly amount of money at the platform.
I understand that you are not a native English speaker which is fine, but you should be aware that another quick marker of typical spam/scam is a poorly translated/written post. Especially when it is supposed to be from company's marketing efforts. There are some communities on the steem blockchain that can help with translation services as well.
