Facebook did some research on self censorship in 2013 (I’m sure there are others but I just happened to remember the paper).

> “Our results indicate that 71% of users exhibited some level of last-minute self-censorship in the time period, and provide specific evidence supporting the theory that a user’s “perceived audience” lies at the heart of the issue: posts are censored more frequently than comments, with status updates and posts directed at groups censored most frequently of all sharing use cases investigated.”

But remember that they can only do that kind of research because they upload, eternally store and data-mine the original text that users delete before ever hitting send. Many people find that unexpected, unethical or outright creepy.
