I occasionally come across content in my feed that I think would be of interest to one of the small communities that I participate in. Think photo or article, not something personal. Is it appropriate for me to crosspost the content? Without asking the OP? What about if I ask but the OP never responds?
Thanks in advance for your thoughts.
Post whatever you want wherever you want, but credit the source. This is important not just for courtesy, but for archival purposes. It leaves a trail that makes it easier for others to find the original if they want to see other work by the creator or information about the subject.
If it’s just a meme, it’s probably not going to matter much, but for original artwork or articles, the author should always be credited when possible, and links make that easier for everyone.
