The insult was "tryhards with bs connections."
I don't see how it's called an exploit if 5 good sparrers streak to 100. Nothing is being exploited. It's just 5 people spending time versus 5 sparrers who aren't as good. It would be an exploit if any plain guild can do this, which admittedly can happen, if there aren't good guilds on to stop it. So I do see how a streak room can be exploited, but I don't see it being as severe of a problem as it's made out to be.
