ok so this is a follow-up on my previous post [is this a bug?] how do i see lemmy content from mastodon

i might have been stupid.

i tried following the !shitpost@lemmy.world community from mastodon and it didn't show any posts or comments there.

i pasted the wrong link. the actually correct link is to follow the @lemmyshitpost@lemmy.world account from mastodon. then it works!

sorry for the confusion

it gets tricky if there is a community and user with that name, dunno which one will be prefered. Only one can be shown, but that’s mastodon’s issue and lemmy built a work-around. Mastodon doesn’t support communities

Lemmy on the other hand will not show user posts that aren’t in communities.

huh, actually, in the activitypub protocol, user IDs are actually URLs. so the actual user id would be https://discuss.tchncs.de/u/basxto or https://lemmy.ml/c/lemmy

if it displays you something like "@basxto@discuss.tchncs.de", that's just because mastodon/lemmy uses a translation service that converts the convenient way to write account IDs to URLs under the hood. activitypub should be fine with a user and community existing with the same name, because their URLs are different. https://lemmy.server/u/name vs https://lemmy.server/c/name

It’s been a while since I ran into that issue and it’s rare to have a collision, but if I started a basxto community, @basxto@discuss.tchncs.de can only map to one. The absolute URLs are meaningless, since @ syntax is supposed to point to something on the current instance. Other URLs I have put into the search field of lemmy/mastodon to convert

For example see @test@discuss.tchncs.de and !test@discuss.tchncs.de

Nice, both link the community here. !-syntax doesn’t do anything on mastodon

If somebody responds to the test account on mastodon, they’ll probably accidentally link the community
