I am sorry that happened to you, it sucks that some people do this.
Truth is tho, despite my initial concerns I have found the online mode generally to be fairly ok. I have spotted numberous commanders milling around and yet have yet to be fired upon in standard beta.
I am not downplaying what happened to you at all, just saying stick with it, hopefully it was bad luck, and, on the bright side, if it was only your free sidewinder, at least it was nothing lost
PS in the interests of fair play, it is possible it could have been in error, and whilst on that note..
.....To the person who I rammed in freeport last night, around 8:30pm BST - I was in my shiny new cobra...
I am so sorry...... I was having ghost keypresses on my X55 after (hopfully) plugging the throttle into the wrong usb port. All I can say is, I am pretty sure it will have cost me a lot more than it cost you! (I was loaded with goods)

My ship suddenly decided to fire up the afterburners whilst I was admiring your ship whilst i was coming into land.
