Oh yeah. Didn't mean to imply that reporting someone could fix the 'hard to kill' issue.
That's just my reaction to it. When someone plays against the human team, I try to kill them; I find out they're human, I report them.
Sometimes it gets really, really hard to kill someone playing against the human team. Hah, I remember this one pair of mush in a game with around 9 inactives; they spored on camera (accident?) but got the weapons and danced around the inactive Ian, and we had so little coordination, we actually could only kill one of them. They kept healing each other (I stole the medikit back during a switch over) and using phagocyte to heal further, and then other problems started to happen, we had to choose to keep slogging away at that one mush or deal with broken O2 tanks and whatnot... that ship finally died like 5 days later, that mush still alive (yeah, we kept trying to kill it.... we just kept missing/only hurting it and it healed/having to not use all our AP to kill it 'cause... other problems and poor coordination). Neither of those mush were reported.
I wouldn't normally (umm... I wouldn't ever?) report a mush for playing against the human team... that's exactly the point. But if I don't have proof someone is a mush and they are being a pain to kill, I'm far more likely to report them right at that point instead of risking forgetting what I think is wrong about their play whenever they finally die or the game ends and I find out if they're Mush or Human.
