Amusingly, Twitter itself could use one. My account (@acangiano) has all of its images censored under "sensitive content" even though they are 100% benign images. No amount of tweets to @TwitterSupport has done anything at all to change it. There is basically no recourse. My account is like 12 years old and has 4.5K followers, so it's not like it's a random spam account, either. ¯\_(ツ)_/¯
