Uber tracks and analyzes a lot more than you'd think -- from your one-night stands to the prevalence of prostitutes in your favorite pick-up location.
But Uber is in damage control mode, under intense scrutiny for its aggressive tactics and threatening journalists. And that means it has been pulling down some of its most interesting (and sometimes edgy) blog posts.
The ride service company's #UberData blog is now squeaky clean.
Among the missing posts: A 2011 study that finds people who are located in the San Francisco neighborhoods with the most prostitution, theft, burglary and alcohol-related crimes order the most Uber rides.
Uber recently took down the blog post, but a cached version is still available online.

A cached version of that blog post is also available, thanks to the Internet Archive project.

Uber CEO Travis Kalanick was forced to apologize publicly after an executive recently suggested digging up dirt on journalists who are critical of the firm. The company is also investigating whether an executive inappropriately tracked journalists' locations when they were riding in Uber cars.
Earlier this month, PayPal co-founder (and Uber rival Lyft investor) Peter Thiel called Uber "the most ethically challenged company in Silicon Valley."
Uber has already made enemies in governments worldwide by taking on the taxi industry. Now it's losing even more friends.
