The point of the article linked above is that a player was complaining that the Sniper award he should have recieved. He wrote a support ticket and here’s what he got for answer:

“Currently there is a bug, in which ramming deprives the player of chance to recieve the award. The bug will be fixed in following patches.”

So, there you have it, confirmed. Allegedly, this bug only occurs when ramming damage is dealt to friendlies, but this is not confirmed.
