@goosecrowcircus If you're talking about faceclaims, the site doesn't have any issues with them. I myself regularly use actors, youtubers, band members and the like to portray my characters. If you're using art, it's always a courtesy to link the artist if you know who it is, of course.
Oh, that's what they're called. Yeah, I don't mind posting their aliases or whatever they identify as publicly in the character sheet, etc. I just wanted to make sure before I outright did anything because all I could see were fantasy threads but I just assume those are the most popular sections of the site.
