Hello Piotr,
I've dug a little deeper to find out which accounts support this guy and his crusade.
Very interesting to take a look on the delegations structure of this account.

I wonder how many people that are struck by his downvotes think about his attack surface since he isn't posting anything and might be immune to downvotes in that regard.
What would be more obvious than striking those who are supporting him?
Hmh... I won't do that though... but I'd love to hear what other by him targeted accounts think about his actions I've dropped an comment in that matter on one of the last SBI articles as well.
Cheers!
Lucky
