### Summary
Reported by @Johnthetester
A user who has opted to tag their own content (**not a user who has been flagged nsfw through the jury**), cannot unflag their own content.
### Steps to reproduce
1. Make an NSFW post.
2. Try to edit out the reasons.
3. Observe changes do not stick.
### Platform information
Cross-platform web.
Reported by John, replicated on Chromium / Manjaro.
### What is the current *bug* behavior?
Cannot remove NSFW tags - blur remains and on refresh original NSFW options remain checked.
### What is the expected *correct* behavior?
User should be able to unflag their own content, so long as they are not flagged as an NSFW channel by a jury.
