(mod: I have no idea tbh? maybe tumblr’s filtering system is being stupid, because there’s no tags that would be considered n/sfw and the blog isn’t flagged as n/sfw?? If any of you know how to fix it can you IM me with a link to it?)
it could depend on who it was reblogged by. Like if someone reblogs it from a blog marked nsfw, that instance would be considered nsfw
