Standard Sleeper site (mobile depot)

So a Standard Sleeper site has a mobile depot in it, it looks like the site has been run, no wrecks from the gas cloud, so, why did they leave it?

The wreck could have already despawned. Whoever ran it, might just refitted for the SSC or for traveling, or to stash the spoils of the site to recover them later.

Humm, I took out the sleeper sentry but decided against trying to run the rest of the site as I didn’t want the same fate perhaps, and probably not worth running.

could have worked on taking out the depot.

Typically, I never do that activity, I stink badly at pvp.
