RE: Steemit, Inc. brand and logo are intellectual property that are protected by law. DO NOT USE THEM.
It is allowed to make use of the steemit logo under the fair use policy. So basically, when writing about news.
Plagiarism specialist, Jonathan Bailey, has written more about the topic here. Most important to remember are the four conditions which need to be met to fall under fair usage:
- the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
- the nature of the copyrighted work;
- the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
- the effect of the use upon the potential market for or value of the copyrighted work.
Check out his further elaboration on the topic, as well as the differences between copyright and plargiarism, in this article.
