Did you know @pixelfed limits Direct Messages to 1-on-1 conversations?
Unlike Mastodon and others, when you mention another account, we treat that as a link instead of including them in the convo and sending them a copy.
Spammers cannot abuse Pixelfed to send the same DM to multiple accounts!
(I'm aware that this breaks group chats which we don't support yet, but I do have a solution in mind)
@dansup @pixelfed IMO ActivityPub (or OStatus, for that matter) is not a useful protocol for chats in the first place, and it should be standard practise to bundle an ActivityPub 'social media' site with an XMPP server if you want one.. They've got all of the nice stuff like e2ee and group chats and moderation figured out already!
