Possibly although the differences of federation between the threadiverse and the rest of the fediverse go way beyond deletes. FEP 1b12 is a whole thing, chipping away at it piece by piece would be slow going.

Yes, a Delete activity is sent to all instances with actors that follow the category/community. Those instances then delete their local copy. In Lemmy/PieFed there is no distinction between deletion and removal.

The deletes are soft so it is possible to un-delete by sending an Undo activity. PieFed keeps soft-deleted posts (topics, in NodeBB language) for a few days then after a week deletes the content from the database.

All of these activities are enclosed in an `Announce` and the http POST is signed using the community key. So in a way the content 'belongs' to the community, not to the original author. With that model of ownership the idea of removal redundant - a post without a community is not a post.

Tangentially - it would be good to come up with a way to move a topic to another category and federate that so the move can happen on other instances, too. We could go off-piste and create a `Move` activity, or use `Remove` (from old topic/comm) followed by `Add` (to new topic/comm) to do the same thing. I feel more inclined to go with `Move` as it's a single atomic operation that either succeeds or fails, despite it not being in the spec.

The AP spec is so badly stretched by various implementation-specific differences that I don't think it's worth being ideological about adherence to it it anymore.

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:

<li>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.</li>
<li>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.</li>

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.
