Chain Ratting-
If you have a spawn with a mil or more bounty, leave smallest ship down to 1/2 armor so the spawn will remain a good spawn and greatly increase the likelihood of a faction spawn.
That's it.
Common misconception- (Always leave one alive)
This isn't a good idea, because chances are if it's a shitty spawn it will continue to be a shitty spawn for a long time.
Always eliminate shitty spawns to 're-roll the dice' on it if you will.
Also please right-click wrecks and select "abandon all nearby containers" so others can put a tractor beam on it and keep the belts clear. Also rumored to increase spawn rate when wrecks are kept clear.
