If we can't get a solution for map hacking, can we please get a permanent ban for the offender?

I have the following case:

Guy is cheating. I report in game, nothing happens. 1 day later, I spend 1 hour recording and uploading video proof that he is cheating. (It is not a case of “he might be hacking” he was very very precise with clicks in fog of war, even to block a palisade with his scout)

He gets banned for 7 days.

After 7 days, he is back cheating. I spend 1 extra hour recording and uploading video to report on website.

He gets banned for 7 days.

Now he is back on the ladder cheating again.

I don’t want to open another ticket.

CAN WE GET A PERMA BAN FOR THIS TYPE OF OFFENSE? What do we need to do?

I know it is hard to change the game engine completely to prevent map hacking, but let us at least do something if someone is actually doing it.
