Mobile Structures Not Showing on zKilboard

Do mobile structures not show up on zKillboard? I’ve noticed sometimes I checked a place to see if a bubble was set up and didn’t see an interdictor or a mobile warp disruptor on the website on the latest kill, but I end up getting killed by a setup with a mobile warp disruptor.

So they were not killed recently. What’s wrong?
Also, zKillboard is not a free intel source. They intentionally postpone location details disclosure.

Zkill dont postpone any location disclosure.

Killmails only get posted to zkill if a player or corp have logged in with the killmail scopes. This is for the final hit character or the loss character.
