There seems to be a misunderstanding with some people regarding the matter. Having spoken to Dodo, who apparently partook in your "point farming", we can confirm that what he explained to us is not exploiting. However intentionally killing yourself so the other team wins and you can quickly gain points is exploiting.
What you mentioned on the post is not the only strategy that was used, which is why some people might have become confused as to what the exact issue is. We'll be speaking to the appropriate people soon, such as Nick, who probably misunderstood your post for the other situation that Dodo explained to us.
