I'd wager that at least 90% of the teams (if not 100%) collaborated to get those scores, and nothing at all was done to prevent it, even when pointed out before the event went live. So if you got "slapped" with this small prize, then so did all the other collaborators and cheaters. It was a poorly designed event, but I'm certain that lessons were learned from it by the event co-ordinators.
Please explain how collaboration is possible, when every party involved would be shown in screenshots or replays. If company A, wins perfectly against company B, then company B proceeds to win against company A, who has no reason to still be running lawltractors after a perfect score, its kind of stupidly obvious they collaborated.
not to mention, there was so many pub teams not even attempting to working together that it was very easy to just have your tier 4s kill the separated pub tier 4s and then proceed to kill all the lawltractors.
