Also, why does a post get federated with the wrong accounts of people tagged as well, even though I removed these before posting and these tags don't show up in the post on the origin server?

And why does Mastodon show images of a cw'd post even though the cw is collapsed, while Pleroma does it right?

And why don't post scopes work properly between platforms...

So many little incompatibilities can pop up in this fediverse thing.
