It should be a signature that is sent together with the ActivityPub Object. Yes, if the signature doesn’t match, the content, whether a post, comment, favorite, upvote, etc… should be dropped.

Here is the source code of the library that lemmy uses to handle incoming objects and you can see that it does a call to verify the signature of the actor:

Messages are sent with a digital signature that only the original instance could craft.

This might have to do with downtime on lemmy.world and lemmy.ml which prevented them from getting the request to delete the comment.

If you visit their homepage. You can fetch your local post if you take that url from their homepage and paste it in the search page of your instance.

Wrong community?

Panem et circenses to calm the masses and also to improve search results for the term ‘reddit’.

Close the windows, curtains and shades during the day, at around 8-9AM. When it’s very warm outside, open windows are your enemy.

Open windows, curtains and shades during the night when temperature is lowering.

Isn’t FOSS Stallman’s definition? Free open source as opposed to just open source

lemmy-ui actually groups them together. It all depends on the app / frontend implementation that you’re using.

actor_id is just the full url of an user. It has the username at the end. That’s why I have censored it.

In case anyone’s wondering this is what we instance admins can see in the database. In this case it’s an obvious example, but this can be used to detect patterns of vote manipulation.

New instances would have a lower voting weight by default.

No need to make all federation under a whitelist. It’s enough to ignore votes from suspicious instances or reduce their weight.

This. It’s only a matter of time until we can automatically detected vote manipulation. Furthermore, there’s a possibility that in future versions we can decrease the weight of votes coming from certain instances that might be suspicious.

Yes. It has both a whitelist federation only mode and a completely private mode.

At this rate we’ll extinguish ourselves before Meta even gets to the third E.

I’d say people worrying about Karma.

Testing.

Oh wait, this is a recent commit. Probably coming in the next version.

How everyone who knew how to had their own personal homepage.

I’d be more inclined to reach out to Louis Rossmann, especially since he’s said he won’t post on reddit anymore. Maybe we can even find a home on lemmy for his right to repair campaign.
