The best we can do is report them. Remember, SE does have to do a full investigation of some sorts before any action will take place. Action will probably not happen immediately, but if the player is truly botting/hacking, they will get banned so long as there is a 'bread crumbs' so to speak - and reports like ours are the first steps.

Something like this tends to require the user to be caught in the act and any logging on their end may or may not allow them to truly determine said player was hacking.
