Typical CCP stuff.
There are already deadspace sites that don’t allow lighting a cyno. Simply apply these settings to all deadspace areas. For all its worth you could also disallow the use of deployables and filaments in deadspace. If you want to get your wrecks, you have to come back after the DED sites despawned. The solution to the issue is already in the old code. CCP just needs to learn to read, understand and apply the old code schemes to contemporary EVE.
