Report to whom? Github, who allows the behavior and therefore doesn’t see anything wrong with it, or the repo admins who have proven they they couldn’t give a rat’s ass about the very thing you’re reporting? The well is already poisoned, there is no reason to think that they’d suddenly change their stance and cooperate.
In this case at least, github (most probably) banned this account, presumably after reports. There are also other stories for github banning accounts for pr trolling kind of behaviours. So not sure if everything is perfect, but at least there are cases such things work.
