Here's an idea of what sort of ads Matt Mullenweg allows on Tumblr (cw: graphic violent content / gun violence)
For far too long these ads have been persistently running on tumblr despite reports of their harmful and graphically violent nature. As I point out, as a user I would be expected to apply a community label for mature / violence to post the video of that ad that runs natively on tumblr.
It's rather disgraceful, and sure, you might not have much pick in ads, but the least you could do is make sure they're not literally gun violence.
