Nope, not at the moment, you need to do manual moderation, which is the best moderation
You'll soon enough notice a trend. Most uploaders don't care to select a category, but if you get it right, you can easily moderate/flag images in a selected category with the "Select all" -> "Flag as unsafe" function. Best practice is to make a habit of checking your site regularly through the day, just like you check facebook (fb is braindead, caring for your site actually gives you something) - so add a shortcut on your phone screen and your moderation is just one click away.
