I've written a simple script for this, called NSFW (because it shows content that is Not Suitable For Work). It will only work if you have 10k reputation (2k on beta sites); otherwise, you probably won't see the post anyway. The link to the revision history will be added to the 'post menu' with the share, edit and flag links.
You can install it here (directly from GitHub).
Source code is here.
Developed and tested with Violentmonkey on Firefox, but should work on other browsers/monkey as well.
