A new contributor, h3ndrik, has made significant improvements to the filtering options for NSFW/NSFL content and I've also added some options to the same form which control when comments are collapsed or hidden.

Previously, NSFW was a yes or no option but now you can choose to have it unblurred, blurred, semi-transparent or entirely hidden.

The defaults values for collapse and hide are:

• when a comment has a score of -10 it is shown but in a collapsed state. You can click on it to expand it and read it. This has always been the case but now you can change that threshold.
• a score of -20 means the comment will not be shown. There is no way to make it visible and no indication that it was ever posted and no temptation to click on it.

You might want to review those settings to make sure they're suitable for you: https://piefed.social/user/settings/filters. If you don't want comments hidden then remove the -20 from that field or set it to -1000.
