Killing Space Spiders gives reputation to Space Pirates
As title says, killing space spiders on the Alien world or its moon will increase your reputation with the Space Pirates.
THIS IS WRONG! Not only makes it no sense for the Pirates to care what you do to the spiders, it also messes up servers: You quickly gain reputation with pirates and makes you likely to get wanted bounties on your head from the other factions.
In other words, killing spiders makes the neutral factions put bounties on you.
