I'm gonna be honest, nooottt realllyyy. Tumblr kinda has a reputation for being toxic, bullying people to the point of suicide, and being a political mess. You can almost post anything you want, including inappropriate stuff, so there's a good chance you might stumble upon that if you aren't actively filtering it out.
I have a Tumblr account, although I haven't posted anything on there so I'm not really sure what feedback you might get. If you make sure to filter out tags about stuff you don't want to see, then I suppose it could be an OK place to post on. Not my first choice as a social media, but it could work.
